7-3 Proving Triangles Similar

You can show that two triangles are similar when you know the relationship between only two or three pairs of corresponding parts.

Problem 1: Using the AA~ Postulate Are the two triangles similar? How do you know?

Are the two triangles similar? How do you know?

Problem 2: Verifying Triangle Similarity Are the triangles similar? If so, write a similarity statement for the triangles.

Are the triangles similar Are the triangles similar? If so, write a similarity statement for the triangles.

Indirect measurement: helps you find lengths that are difficult to measure directly. One method of indirect measurement uses the fact that light reflects off a mirror at the same angle at which it hits the mirror

Problem 4: Finding Lengths in Similar Triangles
