Chapter 7: Similar Triangles Topic 5: Similar Triangle Proofs & More Recall: Three Methods to prove Triangles are Similar – 1) If two angles of one triangle are congruent to two angles of another triangle, the triangles are similar. If: Then: 2) If the three sets of corresponding sides of two triangles are in proportion, the triangles are similar. If: Then: 3) If an angle of one triangle is congruent to the corresponding angle of another triangle and the lengths of the sides including these angles are in proportion, the triangle are similar. If: Then: PROOFS: 1. Given: and Prove: 2. Given: Prove: intersect at D August 2015: June 2015:
