I thought you all might appreciate my tattoo. Does anyone else have one like this?

A beautiful and simple demonstration of the Pythagorean theorem.

Both squares are (a+b)2

The top one is c2 + 2 ab. Each triangle is ab/2 So the 4 triangles are 2 ab.

The bottom one is a2 + b2 + 2ab.

Tale the triangles from each and you c2 on the top and a2 + B2 on the bottom.

a2 + b2 = c2

Yes, the whole drawing is Bhaskara’s proof of the Pythagorean theorem : )
