# Which pairs of polygons are similar? Select each correct answer.

We will use the definition of similar figures to determine the correct option.

## Answer: Options b) and c) are the pairs of polygons that are similar.

Similar polygons appear the same in shape but to check the similarity of a pair polygon, we will use a property of similarity.

**Explanation:**

If two polygons are similar, then their corresponding sides are proportional.

In option a), the ratio of length is 9 : 5 and the ratio of breadth is 2 : 1. Since both ratios are not equal, these polygons are not similar.

In option b), all equilateral triangles are similar to each other.

In option c), observe that the corresponding sides of both right-angled triangles are in ratio 4 : 3
