Question

In $△PQR,\angle R=\angle P$ and $QR=4cm$ and $PR=5cm$. Then the length of $PQ$ is

• A. $4cm$
• B. $5cm$
• C. $2cm$
• D. $2.5cm$

Answer 1

The correct option is A

$4cm$

Given that in $△PQR,\angle R=\angle P$$\Rightarrow △PQR$ is an isosceles triangle.

The sides opposite to equal angles are equal to each other in an isosceles triangle.

So, $QR=QP\Rightarrow PQ=4cm$

Hence, the correct option is A.
