1. Module 16: Lesson 4 AA Similarity of Triangles
Angle-Angle (AA) Triangle Similarity Theorem
If 2 angles of one triangle are congruent to 2 angles of another triangle, then the 2 triangles are similar.
See example #2 on page 863

2. Side-Side-Side (SSS) Triangle Similarity Theorem
If all 3 sides of one triangle are proportional to all 3 corresponding sides of another triangle, then the 2 triangles are similar.
See example #3B on page 865

3. Side-Angle-Side (SAS) Triangle Similarity Theorem
If 2 sides of one triangle are proportional to 2 corresponding sides of another triangle AND the included angles are congruent, then the 2 triangles are similar.
See example #3A on page 865
