A chord of a circle subtends an angle of 60° at the center. What is the angle subtended at a point on the circle in the same segment?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 30°.
The chord subtends 60° at the center, the angle at a point on the circle in the same segment.
Angle at circumference = 1/2 × angle at center (for same arc)
= 1/2 × 60°
= 30°
