Section 7.3: Similar Triangles

Angle-Angle Theorem (AA Thm)- If 2 angles of 1 triangle are congruent to 2 angles of another triangle, then the 2 triangles are similar.

Side-Side-Side Theorem (SSS Similarity Thm)- If the lengths of the corresponding sides of 2 triangles are proportional, then the triangles are similar.

Side-Angle- Side Theorem (SAS Similarity Thm)- If an angle is congruent to another angle in a second triangle, and the length of the two sides that make up the angle are proprtional, then the 2 triangles are similar.

Similarity of Triangles

-Reflexive
