Question : 77 of 100

Marks: +1, -0

A chord of a circle is equal to its radius. The angle subtended by this chord at a point on the circumference is

Solution:

(3)

OA = OB = AB
∴ ΔOAB is an equilateral triangle.
∴ ∠AOB = 60°
∴ ∠ACB

= 60°/2=30°

Angle subtended at the centre by an arc is twice to that at the circumference.
