CHAPTER 7 Similarity Theorems 1. Angle-Angle Similarity (AA~) Postulate:
... If the corresponding sides of two triangles are proportional, then the triangles are similar. 4. Right Triangle Theorem: The altitude to the hypotenuse of a right triangle divides the triangle into two triangles that are similar to the original triangle and to each other. 5. Heartbeat Corollary ...
