Hyperbolic Geometry Theorems 1- 3
Thm 6.1: In hyperbolic geometry, all triangles have angle sum less than 180?.
- Cor: In hyperbolic geometry, all convex quadrilaterals have angle sum less than 360?.
Thm 6.2: In hyperbolic geometry, if two triangles are similar, they are congruent.
Thm 6.3: In hyperbolic geometry, if l and l' are any distinct parallel lines, then any set of points on l equidistant from l' has at most two points in it.
