This video demonstrates how to use Properties of Vertical Angles, Corresponding Angles, Interior Angles of a Triangle, and Supplementary Angles to find all the angles in a diagram. Other Properties discussed include Alternate Interior Angles, Alternate Exterior Angles, Complementary Angles, and the Exterior and Opposite Interior Angles of a triangle. The diagram that is analyzed includes two parallel lines crossed by two transversals.

@bmcrae8 5 лет назад

1) bmcrae 2) MGF1106 EFSC 3) If we look at the angles that are outside parallel lines and on alternate sides of the transversal, we call these alternate exterior angles.

@prestoncohen2743 3 года назад

Preston Cohen (MGF1106 9:30-10:45 Wednesday). My takeaway from this video, is that I now learned some key geometry vocabulary words that are very important to understand. Thanks again.

@MzMath 3 года назад

It is easy to underestimate the importance of vocabulary. I am glad you found it helpful!

@ramonaflowers9799 4 года назад

Roxanne Geldart MGF1106 TR 2pm "Corresponding angles, they are on the same side of the traversal L3, and they're both on top of the parallel lines. This means that angel 6 is equal to the sum of angles 1 and 2. Angle 6 is 114 degrees and angel 2 is 57 degrees. So subtract these two values to find angle 1. "

@kampiskatwan8533 3 года назад

Thank you Ms. Hearn, I took MA 305, and I was Kind of struggle with this problem. But just after watching this Video, I fully understand.

@MzMath 3 года назад

@chadfowler3225 3 года назад

Chad Fowler MGF 1106 9:30 This is really helping with the mathlab homework right now I learned that vertical angles that are directly across from each other are equal

@sybp9780 4 года назад

Sybill Pierre MGF 1106 TR2PM When a pair of parallel lines are crossed by a transversal, the two angles on the same side of the transversal and the same side of the parallel lines are called corresponding angles

@teraynebosch6405 3 года назад

Terayne Bosch MGF1106 M930 One of my takeaways from this video is: " When a pair of two parallel lines are crossed by a transversal, the two angles on the same side of the transversal and the same side of the parallel lines are called corresponding angles."

@Mel-dv8jx 4 года назад

Melissa Denose MGF1106 TR 2PM "When a ray projects off of a straight line forming two angles those angles are necessarily supplementary or add up to 180" this helps so much because i genuinely had no idea how to solve these problems

Jessica Guallimba, MGF 1106 Tuesdays 9:30-10:45, "When two parallel lines are crossed by a transversal and we look at the angles that are between the two parallel lines but are alternate sides of the transversal call these alternate interior angles."

@victoriabusutil5145 2 года назад

Victoria Busutil MGF1106 683 One thing I liked about the video was that you really color code the things and it helped me understand more everytime and you take your time to really show step by step. You show us easy ways to solve the steps in this geometry lesson.

Kerstin haber mgf1106, one thing I liked about this video is how everything was color coded and organized well so i can understand it more.

@naibymax4362 5 месяцев назад

This is Naiby Wu Lu and im from class MGF1106, one take way from this video is that i learn transversal is a line that intersects each of a pair of parallel lines.

@melissacaso5759 3 года назад

Melissa Caso MGF1106 W 9:30 My takeaway from this video is there are different types of relationships we have to remember such as complementary which sums up to 90 degrees and Interior angles of a Triangle which always sum up to 180 degrees. You make this much more easier to understand and this takes a lot of stress out of math for me. Thank you!

@carlyrebar9513 3 года назад

Carly Rebar MGF1106 M 9:30 My takeaway from this video is that complementary angles are right angles split in half so they must add up to 90 degrees.

@lilamoulton5537 5 лет назад

i have a test tomorrow and i didn’t get the concept. thank you so much! but i do have a question. if angles 9 and 10 are supplementary, why aren’t angles 11 and 12 supplementary? thanks

@MzMath 5 лет назад

Actually they are! Good observation. :-)

@jaimeearmesto2368 4 года назад

Jaimee Armesto MGF 1106 Something I learned from this video was the difference between alternate exterior angles and alternate interior angles. Exterior angles are outside of the parallel lines, while interior interior angles are inside of the parallel lines.

@MzMath 4 года назад

Excellent! Important concept!

@alishamccarthy2874 4 года назад

Alisha M MGF 1106 Tuesdays and Thursday’s 2pm-315pm This video was really helpful... Identifying each vertical angle first and if an angle is opposite of one another they are equal ; Each angle has to add up to 180 degrees in an triangle and each supplemental angle add up to 180 degrees... I always had trouble trying to figure out this for years and this video was really helpful thank you soooo much

@angeljohnson6949 5 месяцев назад

Angel Johnson MGF1106 I learned from this video when 2 parallel lines are looked at from the outside the parallel lines on the alternate side of the transversal are called alternate exterior angles.

@jaycenjames9775 3 года назад

Jaycen James MGF1106 M 9:30 My takeaway from this video is that supplementary adds up to 180 degrees and a complementary adds up to 90 degrees.

@MzMath 3 года назад

That's right! Keep up the good work!

@anniefarrugia8570 2 года назад

I like the examples given regarding the relationship of all angles

@arlynn25 4 года назад

MFG 1106 If we are given two angles of a triangle are 66 degrees and 57 degrees in order to find the third angle you must add these two angles and subtract them from 180 degrees.

@MzMath 4 года назад

That's true, Lynn. And it is an example of an application of a very important concept. Keep up the good work!

• Naketa Leiba • MGF1106-837 • Complete ONE of the following statements: o One thing I liked about the video was how you used information to provide the measurement of the angles. There are two parallel lines and two transversals. It forms a triangle and 14 angles. Starting with the two angles in the center if the triangle you can solve for the rest if angles.

@ebjacks2000 4 года назад

@valentinaolano7240 4 года назад

Valentina Olano MGF 1106 My take-away from this video is that supplementary angles will always sum up to 180 degrees. No matter what angle the ray goes in, the angles on either side of the ray will add up to 180 degrees.

@MzMath 4 года назад

Awesome!

@ryancastill0586 4 года назад

@MalevolentRage 2 года назад

Devyn Colon MGF 1106-683 I'm sure I've said it before, but I like that you color code each element of the problem and the solution as you go. It really helps distinguish each part of the problem making it easy to follow and even easier to comprehend.

@kimberlyabreu9959 3 года назад

Kimberly Abreu MGF1106 M930 My takeaway from this video is the meaning of the word transversal. I thought you would say it was a perpendicular line, but the word transversal means "a line that intersects each of a pair of a parallel line."

Before watching this video I knew the names of different angles but did not know the relationship and I can find or solve one angle by using the relationships. Very helpful video to measures any angle with parallel line and transversal.

@candicemurray8528 4 года назад

MGF1106 I didn't realize that the corresponding, alternate interior and alternate exterior are all equal until I watched this video and that it is easier to fill in the vertical angles 1st before doing any other calculation because they are equal.

@MzMath 4 года назад

Excellent!
