journey to the center of a triangle 

This truly feels like we’re watching a restricted video

oh man this version is so much more relaxing that the evangelion one

This was originally going to be the ep 26 of evangelion but they thought it was going to be confusing to people and they changed it

When people say they don't understand trigonometry, I think what they meant is that they are uncomfortable with the array of emotions and characteristics shown by the hypotenuse. Many of which are not commonly considered acceptable for Euclidian geometry

I never thought a simple shape could be so satisfying until at the end all centers converged as the isosceles triangle slowly became an equilateral one

I'm glad the triangle AMV led me to this video - I needed to remember how to find these elements of triangles.

A bit slow at the start, but just like any other anime it starts quite unexpectedly pulling all the disparate pieces together right near the end. A brilliant show, 10/10 would watch again. I hope there's a sequel.

Get in the robot, Pythagoras.

Music is Bach if you hadn't noticed. The prelude of the 8th fugue in the Well Tempered Clavier, in d#. BWV 853

It's insane to think that since is back in the 70s, someone animated all this with traditional hand-drawn animation.

incredible - especially when you consider the production techniques at the time

I hope this blows up like Outside In. It has the same vibe

This is really a cruel angle thesis

The Textronix 4051 had a base price of $6000 (more like $30,000 in today's money) and featured a "storage tube" which made the vector image "stick" to the screen until reset. That means it needed no display RAM to hold a bitmap of the current screen. The resolution was 1024x768. The screen was a monochrome single-color phosphor. They are normally green; I don't know if they had white back in the day. I suppose this was made by photographing the screen for each frame. But, to do color, each color would be drawn by itself and photographed separately. They could be combined using filters to expose a color image.

I could not tell you why I find this animation style so cool to watch. All I can do is say that it is.

I still wanna say that Ramiel is still best girl. Truly a geometrical waifu

The triangle lore is getting crazy

Seriously cool, especially since I remember having worked with the 4051 terminals a little bit in college. There is so much beauty in certain geometric relationships.

This is 3Blue1Brown's origin story

This is great but I prefer the manga

The aesthetics of this can't be described by words

7:49 because of the center point appearing to be one a line, and then that yellow feller just hanging out, and they all move with each other against the perimeter of the triangle, this part always looks to me like we are seeing a triangle being rotated in 3D space and the camera is changing locations. But it’s not quite 3D, it’s off by *that* much. Not quite 4D either, but my mind just makes the connection regardless

The Grand Tour felt like a beautiful dance.

child: "mom can we get the center of a triangle?" mom: "no we have the center of a triangle at home" center of a triangle at home: 6:57

loved watching the triangle move and groove at the end. the circumcenter and orthocenter made it look like it was waving its hands

I wanted The Grand Tour segment to last much longer.

Why didn’t we learn this in trigonometry or geometry? This is such a good way to express so many abstract mathematical concepts, not only intuitively, but quickly too. Thank you for posting this. This is an amazing resource. ❤

I personally want to thank the algorithm for bringing me here after the NGE parody.

Differences between centroid and circumcenter - Centroid always inside triangle, circumcenter can be outside - Line from the midpoint of side of triangle goes to opposing corner for centroid, in circumcenter it is always perpendicular. This is particularly important with obtuse triangles

Geometry is truly the closest thing to witchcraft in this universe

Never thought triangles would be so interesting And they made it mesmerizing to watch and listen

When geometry comes with its’ proofs, it honestly feels like witchcraft. It actually makes so much sense and it’s so easy but it feels too magical to be this simple.

I bet anyone who got here without seeing the anime openings must be very confused by the comments

Almost 3 am and I am relaxing to this, so satisfying... damn

Honestly i just come to this video for the music

Ah yes my favorite RU-vid video genre, shape lore

I will forever be haunted by the knowledge that someone defined the center of a triangle like 2:24 (or 7:14).

I could literally recreate this shot for shot in Desmos Crazy how far math animations have come

I'm a centroid fan myself, but I think that the incenter also works fine in most cases

This movie had such an excellent point

I've learned more about triangles from this than I have ever learned in math class thank you

man I just got this totally randomly in my home page wtf???? its 12 years old!

Every so often RU-vid’s algorithm has a brain fart and then we get this

Same vibes as outside in, but damn i cant not think of the evangelion opening after that one video

I learned centroid and didn't know there were other ways to represent it. Very good simple instructional video perfect for visual learners

This video reminded me of a geometry test I have to take tomorrow, thank you obscure video from 12 years ago, I will not forget this

This is giving me art teacher brings in the large tv because we’re watching a film vibe.

This is really a “trust me it gets super good in season 27” one

Evangelion aside this is seriously impressive for 1976!

8:08 Those dots behave very much like they are on a line through the 3'rd dimension perpendicular to the triangle-plane & intersecting the plane at the red points position. (7:50 except for the yellow point for some triangles, that point behaves like it is on the triangle plane & at a different location for those triangles.)

I could literally watch this forever, it's so good

This looks like something I’d find in the back of my high school’s computer lab and I mean that in the best way possible

I remember when I was taught this in primary school geometry class. Seeing the relationship between circles and triangles for the first time and how I could find the center of any triangle with a compass; I don't think there was a point in my school life that felt as satisfied and made me feel as happy for having learned anything in school as that moment. I was never particularly good at math, I struggled with it all the way up to humble community college, but anything involving geometry and trigonometry always were something special for me

so if this is the anime then i’m assuming the manga is just all the animations drawn as figures proved by mathematical formulas

Almost shown in the presentation, the incenter is the center of the circle inscribed in a triangle. What they showed is how you find it (where vertex bisectors meet), but they could have shown at the beginning with the moving circle that when it increases in size to the point it is touching all sides of the triangle, it's center is the incenter. Because it's the center of a circle, the incenter is equidistant from all sides of the triangle (the distance is the circle's radius).

That part where something happened - I felt that.

This fascinates me for some odd reason. Guess it just goes to show how beautiful and how perfect a shape can really be.

I can’t watch this without inabakumori being played in my head

As an AutoCAD user, I find this quite funny way of doing this. I had found early on, to obtain the CenterPoint of each line using a drafting compass.

This is a video I like to watch on sleepless nights.

Nice anime

This video is just like Outside in. They're both videos uploaded a while ago that are centered on some geometric idea, and both inexplicably appear on my recommended every now and then. Great video, 10/10.

Woke up at night because of hives, this video made me fall back to sleep. I would've stayed up as always if I didn't find it, the music is just that good.

I live here now. This plays in the back of my mind at all times

7:20 when you want to watch more of Top Gear but Top Gear has three new people besides James, Jeremy and Richard

This video generates such strange and unknown emotions...

this video made me fall asleep for 6 hours straight, no joke. good video!

The music to this is excellent!

you know that you're super bored when YT algorithm didn't show you this video, and u willingly watching this video

I think I love the Cornwell's

as a math student i can say that this is a new kind of Art

This video is from 12 years ago and still in my recommendation :D

I used to draw what I just learned were centroids all the time in graphics on a drawing board back in high school & was amazed that the 3 lines always crossed at the same point no matter what shaped triangles I started with & always wondered whether that represented the center of mass of the triangle

This is like an adhd sensory video for adults

I had not realized that the circumcenter, centroid, and orthocenter were colinear. The more you know

12 years ago, 12k likes. NOICE

People need to watch this before entering the Bermuda Triangle

Incenter: angle bisectors Circumcenter: perpendicular bisectors of each side Centroid: the lines from the midpoint of a side to the opposite angle Orthocenter: lines perpendicular to the side that go through the opposite angle

this feels strangely calm and relaxing

Geometry is Zen, when explained and visualized like this. Incredible video.

this was literally my previous geometry lesson youtube knows me irl

no triangles were harmed in the making of this video

This is oddly satisfying

This is almost unsettling for some reason that I can't pinpoint

dude i've watched too much analog horror, I was tensed up waiting for a jumpscare that never came lol

this makes understand each centre of triangles much more effective than any other method of teaching

It's quite a journey

Incentre: angle bisectors Circumcentre: perpendicular bisectors Centroid: midpoint to vertex Orthocentre: vertex to closest point including extended lines

Interesting, it kinda works like perspective

The ending with the equaliateral triangle gave me chills

Incentre: Intersection of angle bisectors. Circumcentre: Intersection of edge perpendicular bisectors. Centroid: Intersection of medians. Orthocentre: Intersection of altitudes.

от развязки мурашки по коже😶 лучшее в мире кинематографа

this is my favorite thing i’ve ever seen in my life

Finally, triangle

Theres something strangely nostalgic about old educational videos with this kind of music and quality. Like a nostalgia for somewhere ive never been

Thanks for the subbed version!

I've watched too much VHS Horror; in here waiting for the impossible shapes.

It's only a matter of time before there is a live action Netflix adaption.

I was watching the Soviet stop motion animated film “Tale of Tales”. This piece (Bach’s Prelude in E-flat minor) plays multiple times, and I could not remember where I had heard it before fairly recently until I finally went “ *GASP* THE TRIANGLE VIDEO!!!!”

this is what the inside of my mind looks like at all hours of the day
