Geometry Section 7-4 A Postulate for Similar Triangles AA Similarity Postulate- If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar. 1. Given: AC // BD Prove: AOC ~ BOD 2. Given: AB BF; RH AF; <1 <2 Prove: HR BF = BA HA 3. In the diagram, LMN ~ PQN. a. Write the statement of proportionality. b. Find m<M and m<P. c. Find MN and QM. d. Why are the two triangles similar? 4. Explain why WVX ~ WZY. 5. Find EH. 6. Tell whether the triangles are similar or not. a. b. c. Classroom Exercises: p. 256 1-11 HW: p. 257-259 2-16 even, 22, 24 d.
