For all those who don't understand, just look at the two different triangles making the big one. One of them has a slope of 2/3 where the other is 3/7 (I think thats what I counted) which in one position, makes a convex angle, and in the other position makes a concave angle.

Today we had to review radians in math class, since we'll be needing those ******* in the mext 2-3 months. So, in order to subtract two radians you make a triangle out of them. Apparently if you substract a radian that's 20cm long from one that's 21cm long, you get a radian that's 15cm long. That makes perfect sense.
I do it out of necessity. I have horrible memory. Either I understand how it works or I don't get anything done, since I have no idea what I'm supposed to do.
so after spending some time in paint i think i got it. while not immediately obvious in the small amount of time given to compare the two triangles, a closer inspection reveals a few differences.
1. The black lines inside outlining the various shapes are of different thicknesses.
2. Each shape is slightly different in size, talking millimeters here. (This is debateable, could just be ****** paint skills.)
Conclusion: My paint skills need some work and this gif is highly debateable but most likely false.
Alright guys its pretty simple stuff i even drew out a diagram to explain it.
It's a pretty simple illusion using two different triangles with very tiny differences, they're both right triangles but one has a 44 degree angle while the other has a 46 degree angle making them seem identical. This tiny difference creates small concave that get over lapped when the two triangles get switched creating what appears to be spontaneous matter.
TLDR: The two triangles have different angles making a concave.
