A video showing how the puzzle is used
Prove Pythagoras' theorem in two ways only by moving surfaces. First using the traditional "Chinese" proof and second using the Bhaskara proof.
It's another path to this knowledge equally valid as Euclid's traditional proof of this foundational theorem of mathematics.
This hand-size puzzle based on the Bhaskara diagram will be available shortly.
The ancient Greeks were the first to see the need to prove for all time, relationships of this type, which were then used to build a mathematical edifice.
