    *head explodes*

    Someone who knows math

    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 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.

    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.
