... If you draw an altitude in an equilateral triangle, you will form two congruent 30º- 60º- 90º triangles. Starting with the sides of the equilateral triangle to be 2, the Pythagorean Theorem will allow us to establish pattern relationships between the sides of a 30º- 60º- 90º triangle. These relation ...

... Saccheri-Legendre Theorem If 4ABC is any triangle, then the angle sum S(4ABC) ≤ 180◦ . It is interesting that we can prove this theorem in Neutral Geometry without any assumption of a parallel postulate, but the road to get there has a few stops along the way. We will assume without proof the follow ...
