# State whether the following quadrilaterals are similar or not:

**Solution:**

Two polygons of the same number of sides are similar if

- all the corresponding angles are equal.
- all the corresponding sides are in the same ratio (or proportion).

In quadrilaterals ABCD and PQRS,

AB/PQ = BC/QR = CD/RS = DA/SP = 3/8

⇒ Corresponding sides are in proportion.

But ∠A ≠ ∠P; ∠B ≠ ∠Q

Thus, corresponding angles are not equal.

No, Quadrilateral ABCD is not similar to Quadrilateral PQRS.
