8 If a chord AB subtended an angle 80° at centre, then what will be the measure of angles subtended by same chord in the same segment of the circle at point P and Q? A. Chord AB subtended on angle of 40° at both points.​

Answer 1

Answer:

An arc of a circle is any part of the circumference. The angle subtended by an arc at any point is the angle formed between the two line segments joining that point to the end-points of the arc. In the following figure, an arc of the circle shown subtends an angle α at a point on the circumference, and an angle β at the center O.
