Two polygons having the same number of sides are similar if
Atheir corresponding sides are equal
Btheir corresponding angles are equal only
Ctheir corresponding angles are equal and their corresponding sides are proportional
Dtheir areas are equal
Answer & Solution
Correct answer: C. their corresponding angles are equal and their corresponding sides are proportional
For polygons, both conditions are required: corresponding angles must be equal and corresponding sides must be in the same ratio. Either one condition alone is not sufficient in general.
