sPythagoras

I had a minor brain wave when reading this wonderful book by my favourite author. In it he mentions a good idea for teaching Pythagoras proofs. Take a square photograph, and chop it up in the exact proportions of a dissection proof, then get students to rearrange it to ‘prove’ the Pythagorean theorem. A simple idea, and one I’m sure has been used countless times before and since. I immediately took to the idea and went about planning it out. I’ve always had a bugbear that students are usually shown only one proof of the Pythagorean Theorem, when in fact, there are hundreds. So I wanted to dissect several images in several different ways. Granted, this negates all proofs apart from proof by dissection, but it’s a start. Pythagoras lends itself nicely to sPythagoras… so… behold, the James Bond Pythagorean Proofs, featuring six James Bond actors, and six different dissection proofs:
