Pythagorean Theorem Without Words

Thu 26 March 2020 | tags: math art-maybe proofs

Introduction

The pythagorean theorem lends itself easily to a wide variety of visual proofs. Try and figure out the logic behind them. I find it to be clearer in some cases than others.

This is partly inspired by Neal Stephenson's "Anathema" as well as numerous other visual proofs online. There's a lot of really good ones, but I think there's some room for improvement.

Attempt 2

Attempt 3 (based on Euclid)

Bonus (Perpendicular Bisector Theorem)

I don't remember why I made this, but I suspect it has something to do with Fortune's algorithm.
