8.5 Proving Triangles are Similar
Theorem 8-2 : SSS Similarity: If the corr. Sides of 2 tris are proportional, then the tris are ~

Theorem 8-3: SAS Similarity: If 1 angle on 1 tri is cong to an angle of a 2nd tri and the lengths of the sides including these angles are proportional, then the tris are ~
