      The proof is a chain of logic. Each step is justified, and then the Laws of Detachment and Syllogism connect the steps to prove the theorem. Vertical angles are angles on opposite sides of two intersecting lines. In the figure at the right, (1 and (3 are vertical angles. (2 and (4 are also vertical angles.

      – two coplanar angles with a common vertex and a common side between them. Vertical angles – the non-adjacent angles formed by two intersecting lines. Complementary angles – two angles whose sum is 90 degrees. Supplementary angles – two angles whose sum is 180 degrees. Perpendicular lines – two lines that intersect to form right angles.

      Proof This is a direct result of Saccheri-Legendre. Now let’s look at a really amazing quadrilateral: a Saccheri Quadrilateral. Angles A and B are right angles, the 2 sides are congruent. In Euclidean Geometry, angles D and C are right angles. In Hyperbolic Geometry, they are acute angles. In Spherical Geometry, they are obtuse angles.
