WebbThe triangle proportionality theorem states that if a line is parallel to one side of a triangle and it intersects the other two sides, then it divides those sides proportionally. Thus, with the aid of the triangle proportionality theorem, we can solve for the unknown in a triangle divided proportionally. WebbThe module is about the Triangle Similarity Theorem. After going through this module, you are expected to illustrate the similarity and prove the conditions for similarity of triangles. 1 SAS similarity theorem. 1 SSS similarity theorem 1 AA similarity theorem 1 right triangle similarity 1 Special right triangle theorems.

The basic idea is that the two triangles are similar, because their corresponding angles are the same. From this (which, of course, is the essence of the proof), the corresponding sides are proportional. Sometimes believing that a theorem is true just comes down to understanding the proof.
