Geometry - Inscribed Angles 

To think these kids already have graduated and moved on with their lives is crazy!

you should run seminars around the world on how to teach students, I Love your videos, you have really helped me alot in ways my teachers couldn't, i wish i could thank you in person. from Australia!!!

no wonder all your students listen to you XD you're a great teacher :) thumbs up and hats off to all teachers like you :)

SO SO SO GRATEFUL for these videos. I actually feel like i'm in class with you, not disconnected like I feel when I'm in my actual geometry class. My geometry teacher at school puts me down a lot, and makes me feel like I'm stupid, but when I'm watching your videos, I feel like I've achieved so much. This has been such a hard year for me in geometry and my teacher sucks so bad, so just THANK YOU! You are what all teachers should be like.

Thanks man you saved my grade in math, I wish my teacher taught as well as you

I need u to be my teacher, right now !!!!!!

dude you are no doubt the best teacher in the world

I love your teaching. I am going to college to be a math teacher and you inspire me to be fun, positive and energetic.

Firstly, you are really weird. Secondly, your videos are really helpful. Thanks, this clears up a few things for me.

this is weird, im already in precal2 college, i didnt learn any of this ever in high school. i just happened to click the video cuz i saw a math teacher in Egyptian costume lol. but this is pretty easy though

I've been struggling with this a lot and I now understood it in 10 minutes, why is there school?

Aaaammmmaaaazzzing!!!!! A teacher that can TEACH!!!!! And is tolerant/nice!!!!! On the last problem, though, since there's an inscribed quadrilateral, you can do 100+x=180 and 45+y=180. (But you were probably trying to get the students to think... ;)

Yay Math? More like yay me, thank you so much. This helped me so so much! It's been 3 years and you are still saving lives!!

How does this guy manage to make math interesting?!?

i just spent 12 hours for a week trying to learn this concept for a unit test. I just learned it in 20 min. You are the best! Thank you for making math ( which I hate) actually fun!

I found this while looking for help for my daughter (who is pictured by this comment) who is struggling with graphing /equations, or something like that. I can't help her at all with math, not my thing. But, I can't stop watching yaymath videos, he truly loves to teach and cares if the students learn and understand what he teaches, which is math. You can see and understand why these kids probably look forward to his class. How many kids do you know who enjoy going to math class? Most fall asleep I assume. Not here, they are ingaged, having fun and learning. Good Job!

I really wish you were my teacher, you seem so energetic and in to what you're teaching, i'd actually be able to stay awake easier.

Wow this 22 min video taught me more the man hour math class. GG sir

Imagine having this guy as a teacher. Fantastic work. This is what makes kids and students truly understand and even like math. Which makes the world a better place and moves us forward as a species. It’s evolution in progress what we’re seeing right here. 👌👌

This video made it so easy for my daughter to learn inscribed angles and arcs ,thank you for being such a great teacher

I watched this thinking it was going to be just corny but I actually learned shit lol thx I have my hw done for class in a few minutes :p

Need more teachers like him fun and educational at the sametime

Love all your videos! I don't have to go to tutoring! Saves me so much time.

One word to describe your videos "NICE"

Great lesson! There's a quicker and faster method my Geometry teacher taught me at 11:55. Opposite angles in the shape inscribed into the circle (forgive me if I don't remember the name of the shape) are supplementary so 180-100= 80 and 180-45=135. Because we know that the half arcs are 180, we would subtract the given angle, which is 100, from 180 to get the opposite angle; which is 80, and then do the same thing for the other given angle.

Learned so much more from your one video than 3 weeks of school with my math teacher, those kids are lucky to be taught by you, the class seems fun and educational :)

You're an amazing Math teacher sir

Such a awesome teacher if it weren't for your videos I don't know how I would understand these concepts

There is an easier way to find the last angle(135) Quads are 360 degrees since you already have 3 angles the Last angle = 360- (100+80+45) which is 135 degrees. What I am saying is that finding the last arc is not necessary. I enjoyed this video. He is a great teacher.

You are the best freaking teacher in the world!

Thanks Pharoah mathemaGYPTIAN... that was awesome.

You make understanding math a lot easier. Thank you.

i dont knw if ive ever messaged you i am from jamaica and we do cxc maths here this is helping me sooo much a million thanks to you i kno i have a shot at passsing youre awesome man !

this is super cool I actually understand this and im in two math classes you're an awesome teacher

Wish I had a teacher like this!

Good argument for solving the problem practising inscribed angles but you could have solved more easily, using the rule of Cyclic quadrilateral, that opposite angles in a cyclic quadrilateral add up to 180 degrees !

Hello!:) I just wanted to say I watch your videos before my geometry test for review. it is so helpful! i really wished i had you as a geometry teacher, you are always full of energy and very engaging! thanks so much for making these videos!

I love your videos your videos are really helpful I love the way you are teaching you made the math more easier

What an inspiring and awesome teacher. So enthusiastic to help his students

iv been watching your vids since 9 th grade im going to 10th grade know great teaching methods and u really helped me

im doing geometry online because i fell behind and failed last year and this helped me a lot compared to the instructions given to me online

I realize its not drawn completely to scale, but the 80 angle is clearly more then 90 degrees- looks like a 100 degree angle. It was difficult to comprehend all the angles with that optical illusion until I redrew a new circle myself to try and see how all those angles would actually work in the circle. I think you should put in one of those pop up messages you do :) Just saying, "yes this line is a little off, but the angle really is 80!"

Well I was originally searching for is cribbed circles so that I can solve by homework. This video helped with som much more! Thanks you :)

Love the way you work sir.. wow.. that would make not only my day, but my whole year.. wow

you make maths. lessons really fun

You have helped me so much! I had this one problem I kept getting wrong and when I watched this video, I figured it out immediately!

Great lessons. I'm using videos to help me prep for GMAT. To at least have the concepts. You are one the better video series I found to clearly explain the concepts. thanks.....

Such an inspiration! your definately my idol.. keep the videos coming!!!

Very impressive and creative way to teach eager students! Me and my nephew stumbled upon your channel by accident and instantly got hooked on. Good job and hope you do well! You should travel the world and do seminars to teach other teachers how to teach!!!! :-)

So much better than my actual teacher, who legit told us what our homework was and didn't tell us how to do it.

Supplemental angles equal 180' : angle x is 45' + angle y is x'; so 180' - 45' = 135'; angle y = 135'.

Thank you so much for these videos! They've really helped me get good grades in my Geometry class and they give me a better understanding of what we are learning in class. ^.^

Woahh i actually understood this ive been struggling with it for soo long thank youu so soo much

i love this! like i really hated math before but after i watched videos like this makes me love math! iam excited for our exam tomorrow :) :) :) :) ...thank you for making this :) hope iam not yet late haha xD watching in 2015...:) :) :) ...

I enjoyed your videos a lot! I am not a student but I learn a lot from you, especially your humor and explicit teaching! I am taking special education MAT program and many students are not motivated and humor and fun definitely can keep them engaged. Is there a way that you can relate math to real life ? Because many students in my class seem to lose interest learning unless it is life related.

This made this so much easier. Thanks!

AMAZING!!!! THANKYOU, this will definitely help me on my Geometry EOI. THANKYOU!!! U MAKE SO MUCH SENSE

why are you dressed as pharaoh?

An easier way to find the angles in the last question is to do 45+x=180 and 100+x=180 . But thank you this helped a lot

i loved your videos they been a great help

you r a great teacher

your videos are helping me a lot, thank you very much!!!...YAY MATH!

your videos are honestly so helpful

You are very welcome for watching!

i love your videos, great way of teaching. good job man

Nice work fellow teacher. You could also explain to the class how this proves that the internal angles of any quadrilateral adds up to 360.

Thank you so much! i wish you are my math teacher very good explanation

very nice presentation...its fun... for the last angle, we can add up all the three angles and subtract it from 360...the inscribed figure is a quadrilateral..:)

On the last problem: Would the imaginary line from 45 degrees straight to the other end under 90 degrees be supplementary? 45+x=180 -45. -45 X=135 So 135+100+45+x=360 280+x=360 -280. -280 X = 80 Is it like that for all problems?

it was really cool I can Get enough To know that I understand circles IN ONLY 20 minutes AMAZing UNLIKE on my actual lesson :) thank u Sir MathGyptian

Nice video. I like your way of Teaching. Thank you sir.

lol this is awesome, I wish I had a teacher like this when I was in school

Sir, im confused. The last example is not consistent that the total angle of a circle is 360 degrees since 90+200+270+160 is 720.

16:19 actually 100+45=145 and 145*2 makes 290. So they do combine a little for that one

There was a much easier way for solving that last question. The interior shape was a quadrilateral so it had 360 degrees and there's a rule that states that the opposite interior angles are 180 degrees so in this case 180- 45= 135 and 180- 100 is 80 degrees.

thankyou sir you have made me understand smething that i missed in primary level I love the video you need to come in kenya

Great. Thank you. Is there a video that precedes this?

i am going to take the eoc and this is helping me a lot thank you

I have an Exam tomorrow and I am watching this, i understand it way more than how my teacher teaches!

this entertained me. and helped me.

This is great stuff. Keep up the good work!

You're so funny and I like it 😂😂. Thank you so much for this sir! 🙂 God bless you.

The fact he went in the class in a costume Wish he was in my class he cures the boredom

i undrstand many thing that i did know earlier great teaching skills

Thank you this helped!

thanks this helped me a lot and your videos are really funny and helpful

very helpful! great teacher! thanks so much !

I hope this will save me during my finals

Helped me with my homework,thanks a lot

Was the guy who asked how it was 20 at around 11:30 the dean or something?

i would love to have you as a teacher.. i’m so jealous

Could you record a whole session? I'd like to know what you do in an entire session.

2:10 for central angles is a measure of the arc. you have gone over it . please which video?

Is there a difference between included arc and intercepted arc?

"delete the curious"..thats funny.

yeah ... finely finding lovely teacher and lovely lessons hahaha love ur lessons love u :) im from Kurdistan

An easier way of solving the angles 20:29 is to do circle theorem rule 4 opposite angles in a quad add up to 180 degrees.

i love this vid because I really understood well thank you Mrs.

You're awesome !

oh my god you are amazing. i hate math but you make me want to learn it.
