Question

If the line from the centre of a circle to a chord (other than the diameter) bisects the chord, then the angle between the chord and the line is:

• A. ${30}^{\circ }$
• B. ${45}^{\circ }$
• C. ${60}^{\circ }$
• D. ${90}^{\circ }$

Answer 1

The correct option is D ${90}^{\circ }$

A straight line drawn from the centre of a circle to bisect a chord is at right angles to the chord. Thus, the angle between the line and the chord is ${90}^{\circ }$.
