The angle PRQ is 60° and the length of side PR is 20 cm.PQRS is a cyclic quadrilateral. **the measure of the angle subtended by an arc at the center of the circle is double of the measure of angle subtended by the same arc on the circumference**. Also, the sum of the opposite angles of a cyclic quadrilateral is 180° . Thus, the required measure are m∠PQR = 60° and m∠PSR = 120°.The vertices of the triangle PQR are **P, Q and R**. The side opposite to a vertex is called a base. The above figure of a triangle PQR, QR is the base when the vertex is P.

## How do you find the PQR angle?

PQRS is a cyclic quadrilateral. **the measure of the angle subtended by an arc at the center of the circle is double of the measure of angle subtended by the same arc on the circumference**. Also, the sum of the opposite angles of a cyclic quadrilateral is 180° . Thus, the required measure are m∠PQR = 60° and m∠PSR = 120°.
