What did Pythagoras sacrifice when he discovered his theorem?

Answer 1

I have never heard of Pythagoras sacrificing anything. In fact, he didn't discover that the squares on the sides of a right-angled triangle add up neatly. The Egyptians knew that when they built the pyramids, and probably any self-respecting engineer from 4000 BC on used the fact. It's called Pythagoras's Theorem because Pythagoras wrote books which mentioned it and have been preserved. Nobody else seemed to bother much about making it a big deal.
