If AB is a chord of a circle, P and Q are the two points on the circle different from A and B, then(a) ∠APB = ∠AQB(b) ∠APB + ∠AQB = 180° or ∠APB = ∠AQB(c) ∠APB + ∠AQB = 90°(d) ∠APB + ∠AQB = 180°

If AB is a chord of a circle, P and Q are the two points on the circle

1.	If AB is a chord of a circle, P and Q are the two points on the circle different from A and B, then(a) ∠APB = ∠AQB(b) ∠APB + ∠AQB = 180° or ∠APB = ∠AQB(c) ∠APB + ∠AQB = 90°(d) ∠APB + ∠AQB = 180°
Answer» If AB is a chord of a circle, P and Q are the two points on the circle different from A and B, then (a) ∠APB = ∠AQB (b) ∠APB + ∠AQB = 180° or ∠APB = ∠AQB (c) ∠APB + ∠AQB = 90° (d) ∠APB + ∠AQB = 180°
