1 7.2 : Similar Polygons Similar polygons have:
Congruent corresponding angles Proportional corresponding sides Scale factor: the ratio of corresponding sides A Polygon ABCDE ~ Polygon LMNOP L B E M P Ex: N O C D

2 If ΔABC ~ ΔRST, list all pairs of congruent angles and write a proportion that relates the corresponding sides.

3 Determine whether the triangles are similar.

4 A. The two polygons are similar. Find x and y.

5 If ABCDE ~ RSTUV, find the scale factor of ABCDE to RSTUV and the perimeter of each polygon.

6 If LMNOP ~ VWXYZ, find the perimeter of each polygon.
