ECZ 2016 · O-Level Paper 1 — Circle Theorems
PR is a diameter of a circle with centre O; Q and S are on the circumference. The tangent at P meets QS produced at T, with ∠PQS = 26° and ∠QPR = 42°. Calculate PRS.
- A. 64°
- B. 26°
- C. 48°
- D. 42°
Verified working — step 1
∠PRS and ∠PQS stand on the same chord PS in the same segment, so ∠PRS = ∠PQS = …The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
