State whether the following quadrilaterals are similar or not.

To do:

We have to state whether the given quadrilaterals are similar or not.

Solution:

Two figures are said to be similar if their corresponding angles are congruent(equal) and the corresponding sides are in proportion.

 In the given figures,

The sides of quadrilaterals $PQRS$ and $ABCD$ are proportional but their corresponding angles are not equal.

Therefore,

The given quadrilaterals are not similar.
