Question

A chord of a circle is equal to its radias.Find the angle subtended by this chord at center of circle​

Answer 1

Answer:

Let AB be the chord of the circle with center O. Given that AB = Radius of the circle. ∴ ΔOAB is an equilateral triangle. Also, angle subtended by an arc at the center of the circle is twice the angle subtended by it at any other point in the remaining part of the circle.

Answer 2

Answer:

Let AB be the chord of the circle with center O. Given that AB = Radius of the circle. ∴ ΔOAB is an equilateral triangle. Also, angle subtended by an arc at the center of the circle is twice the angle subtended by it at any other point in the remaining part of the circle.
