Question

the relation between an Arc of a circle, radius of that circle and the angle subtended by the arc at the centre of the circle is​

Answer 1

Answer:

Congruent arcs of a circle subtend equal angles at the center. The angle subtended by an arc at the center is double the angle subtended by it at any point on the remaining part of the circle. Angles in the same segment of a circle are equal. An angle in a semicircle is a right angle.
