In the figure, O is the centre of the circle and POR = 120°. Find PQR and PSR


Answer :

Given, POR = 120°


We know that “Angle subtended at the center is twice the angle subtended at circumference by the same chord”.


PQR =


PQR =


PQR = 60


Now, PQRS is a quadrilateral and angles on the opposite sides in the quadrilateral are supplementary.


PSR = 180- PQR


PSR = 180-60


PSR = 120o
