Not so much a trick of the eye so much as a trick of math. Shaving fractions to make up for the missing square.

arctan(3/8) =! arctan(2/5), this is silly. The smallest angle of the green triangle is 20.556 degrees, where the angle of the triangular part of the orange section, meaning if you cut it into a square and triangle, is 21.801 degrees. These shapes don’t even fit together. If the angles were the same, then yes, I’d be shitting bricks.
*head explodes*
Look carefully at the inclines.
3/8 = 15/40 != 16/40 = 2/5
There’s a very narrow empty space between the upper and the lower part in the “65” picture, and it has the same surface as one box.

Yeah I noticed it too, good eye.
i’ve known about this fallacy ever since i was 5 years old… 8/
I’ve never taken the time to work this one out but I’ve always assumed that there had to be some tricking the eye thing happening with this one.
