...that makes a circle, silly !

you are doing it wrong! :D be creative

let me take you by the hand, you know the Pythagoras only works for triangles with a 90° angle. It is also completely fine if you end up with another square in your square.

less touching my hand, more math, please.

And as far as Pythagoras goes, he works at the local kebab shop the last time I heard.
Only pizza comes in triangles, everyone knows that! ....Durr.
