Question

similar polygons have corresponding angles that are congruent and corresponding sides that are... congruent similar proportional equal

Explanation:

Similar polygons have congruent corresponding angles and proportional corresponding sides. This is a fundamental property in geometry. Congruent angles mean they have the same measure. Proportional sides mean the ratios of the lengths of corresponding sides are equal. For example, if one polygon has side lengths \(a,b,c\) and a similar polygon has side lengths \(ka,kb,kc\) (\(k\) is a positive real - number called the scale factor), then the sides are proportional.

Answer:

proportional
