 Hello and welcome to this session. Today I will help you with the following question. The question says, state whether the following quadrilaterals are similar or not. These are the two quadrilaterals PQRS and ABCD given to us. We have to check their similarity. We know that two polygons of the same number of sides are similar if the first condition for this is corresponding angles are equal if their corresponding sides are in the same ratio that is proportion. This is the key idea to be used for this question. Let's move on to the solution. As you can see both these quadrilaterals PQRS and ABCD have four sides. Now let's check if the corresponding angles are equal or not. Consider the quadrilateral ABCD in this we have that angle A is 90 degrees but angle P which is the corresponding angle to angle A is not 90 degrees. So we say that angle A is not equal to angle P. Again angle B is also 90 degrees but angle Q is not 90 degrees. Also angle B is not equal to angle Q. Then angle C is also 90 degrees but angle R which is the corresponding angle to angle C is not 90 degrees. So angle C is not equal to angle R. Then again angle D which is also 90 degrees is not equal to angle S. Thus we say that the corresponding angles of the quadrilateral ABCD PQRS not equal hence the condition one is not satisfied. So we say that the two quadrilaterals are not similar. Hence the final answer is no. So hope you enjoyed the session. Have a good day.
