Any angle whose vertex is at the centre of the circle is called
Central angle
Straight angle
Reflex angle
Right angle
As shown in the figure, Angle POQ is a central angle of the circle C (O, r). The vertex of the angle is O the centre of the circle.
O is the centre of the circle. AB is a minor arc of the circle. The angle subtended by AB at centre, ∠AOB = 110∘, then angle subtended by the arc at any point on the circle say ∠APB is ____, where P is any point on the circle.
O is the centre of the circle. AB is a minor arc of the circle. The angle subtended by AB at centre ∠AOB = 110∘, then angle subtended by the arc at any point on the remaining part of the circle i.e. ∠APB is (where P is any point on the circle)?
