4.2 Triangle Congruence by SSS and SAS
... 4.3 Triangle Congruence by ASA and AAS • You can prove that two triangles are congruent without having to show that all corresponding parts are congruent. – You will prove triangles congruent by using one pair of corresponding sides and two pairs of corresponding angles. ...

... First, let as prove that the lines containing two “almost adjacent” rays A1 A2 and A4 A3 are disjoint: i.e. suppose B = A1 A2 ∩ A4 A3 . Then the triangle A2 A3 B has at least two non-acute angles, which contradicts to the fact the angle sum of a hyperbolic triangle is less than pi. Similarly, assumi ...

Polygons I - Henri Picciotto
... A polygon is a closed figure with straight sides. An n-gon is a polygon with n sides. A convex polygon is one where no angle is greater than 180°. 1. Is there such a thing as a nonconvex triangle? If so, sketch one in the space at right; if not, explain why not. 2. Is there such a thing as a nonconv ...
