Question

$\angle AOB$ in the below image is an example of

• A. acute angle
• B. obtuse angle
• C. reflex angle
• D. zero angle

Answer 1

The correct option is B obtuse angle

A complete turn in a circle covers ${360}^{\circ }.$
$\therefore \angle AOB={360}^{\circ }-{260}^{\circ }={100}^{\circ },$ which is greater than a quarter circle but less than a half circle, so it is an example of obtuse angle.
