That's an illustration of the proof. Here is a more modern, animated example: https://upload.wikimedia.org/wikipedia/commons/2/29/Pythagorean_Theorem_Proof.gif https://upload.wikimedia.org/wikipedia/commons/2/29/Pythagor... The Chinese proof looks more like this one though: https://i.stack.imgur.com/Ylzhg.gif https://i.stack.imgur.com/Ylzhg.gif There is also explanation in the annotations.

- pash 10y agoSearch for the phrase "proofs without words" [0, 1]. There's long been a column in Mathematics Magazine by that name featuring proofs in this style, and there is a book of the same title published by the Mathematical Association of America (which I think collects proofs from the magazine column). Lots of examples from other sources will also show up in a web search. 0. https://encrypted.google.com/search?hl=en&q=proofs%20without%20words https://encrypted.google.com/search?hl=en&q=proofs%20without... 1.
