8.5 Proving Triangles Similar

Theorem Side-Side-Side Similarity (SSS Sim) If sides of 2 triangles are in proportion, then the triangles are similar.

Theorem Side-Angle-Side (SAS Sim) If an angle of two triangles are congruent and the side including the angle are in proportion, then the triangles are similar.
