Exercise 22 Page 560

If two polygons are similar, then their corresponding angles are congruent and the lengths of their corresponding sides are proportional.

No, see solution.

Practice makes perfect

Polygons that have the same shape are called similar polygons. If two polygons are similar, then their corresponding angles are congruent and the lengths of their corresponding sides are proportional. With this information in mind, let's examine the given figures.

given figures

Let's check whether corresponding sides are proportional. 3/5 = 3/5 ≠ 5/9 * Since all of the proportions are not the same, the polygons are not similar.
