A chord of a circle is equal to the radius of the circle find the angle subtended by the chord at a point on the monor arc and also at a point on the major arc.

Explanation

The chord AB is equal to the radius of the circle.

OA and OB are the two radii of the circle

In `triangleOAB`

AB=OA=OB (radius of the circle)

Here, `triangleOAB` is an equilateral triangle.

`AOC=60^*`

`ACB=1/2xx60^*=30^*`

Now, ABCD is a cyclic quadrilateral.
