In the diagram, P, Q, R, S are points on the circle with centre O and angle PQR = 68°. TRU is a tangent at R. Find angle PRO.

Verified working — step 1

OP and OR are both radii, so triangle POR is isosceles - its base angles at P and R are equal.

The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
