## Theorems

**Similarity Theorems**

1. AA similarity: If two angles of one triangle are congruent to two angles of another triangle, then the two triangles are similar.

2. SAS similarity: If one angles of a triangle are congruent to one angle of another AND the length of the sides including these angles are proportional, then the two triangles are similar.

3. SSS similarity: If corresponding sides of two triangles are proportional, then the triangles are similar.
