Question

The chord of a circle is equal to its radius. The angle subtended by this chord at the minor are of the circle is

• A. ${60}^o$
• B. ${75}^o$
• C. ${120}^o$
• D. ${150}^o$

Answer 1

The correct option is A

${60}^o$

The chord of a circle = radius of the circle

In the figure, OA = OB = AB

$\therefore \angle AOB={60}^o$ ($\because$Each angle of an equilateral = ${60}^o$)
