  1. 8-3Proving Triangles Similar One Postulate Two Theorems

  2. Postulate 8-1 Angle-Angle Similarity (AA~) Postulate • If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.

  3. Theorem 8-1 Side-Angle-Side Similarity (SAS~) Theorem • If an angle of one triangle is congruent to an angle of a second triangle, and the sides including the two angles are proportional, then the triangles are similar.

  4. Theorem 8-2 Side-Side-Side Similarity (SSS~) Theorem • If the corresponding sides of two triangles are proportional, then the triangles are similar.

  5. #1 Using the Similarity Theorems What theorem or postulate state that the two triangles similar? V W 450 S 450 1. 1. R B 2. 2. 3. 3.
