I have to prove this statement: Euclidean parallel postulate equivalent pythagorean. Someone gave me the proof of pythagorean but I don't see the link between Euclidean parallel postulate and pythagorean. Someone helps me, please.

    Among the proofs, 112 proof for pythagorean, I tried to figure out which one using Euclidean parallel postulate but I failed. Surely, to show the Euclidean implies pythagorean, we need a proof which used // postulate to prove to show pythagorean implies //, we do backward. But it seems I failed on figuring out which proof has both sides like that. :(
