ECZ 2016 · GCE Paper 1 — Circle Theorems
In the same diagram (TR a diameter, QR ∥ PS, TÔS = 80°, TR̂P = 10°), find PŜT.
- A. 20°
- B. 10°
- C. 80°
- D. 40°
Verified working — step 1
PŜT and PR̂T (= TR̂P) both stand on the chord PT from the same side of the circle, so they are equal: PŜT = …The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
