Question 21
Circle TheoremsThe diagram is a circle centre O. If ∠SPR = 2m and ∠SQR = n, express m in terms of n.
- A.m = n/2
- B.m = 2n
- C.m = n − 2
- D.m = n + 2
Show the answer and explanation
Answer: A (m = n/2)
Explanation
∠SPR and ∠SQR stand on the same arc SR, so they are equal: 2m = n and m = n/2.
