Visual Pythagoras

Reading Edward Tufte’s “Envisioning Information“, I came across a simple graphic, originally published in the Chinese mathematics treatise Zhou Bi Suan Jing (or Chou Pei Suan Ching) that impressed with its simplicity. It’s a visual, geometric way of proving the Pythogorean Theorem that was published around 2,000 years ago. If you compare it with Euclid’s proof, this picture is worth about 500 words.

Any mathematicians out there know that there are many ways to prove the theorem attributed to Pythogoras – I like the simple elegance of this one. Here’s my redrawing of the Chinese original.
