Meme is a screen cap of a FB post. I shared an image of a keyhole like shape where the radius of the circle, is the same length of each wall, AND the bottom of the key slot.
It reads 'Behold a Square' at the top.
And bellow 'A shape with four sides of equal length, with four right angles.'
I added the comment 'Chaotic Lawful' in my post on FB.
