WebAug 28, 2013 · Saccheri-Legendre Theorem is really the thing to look at, and see if any of the steps in the proof are objectionable to you. Saccheri at least was one of the mathematicians who was trying to prove the parallel postulate from the other Euclid axioma, so was pretty careful not to use them in his work. – coffeemath Jan 26, 2015 at 8:05 WebAug 6, 2015 · Saccheri-Legendre theorem.
