Question

In the figure, given below name:

(iv) two reflex angles

Answer 1

Finding the two reflex angles.

We know that an angle more than ${180}^{\circ }$ but less than${360}^{\circ }$ is called reflex angle.

Therefore, using protractor we saw that following angles are more than ${180}^{\circ }$and less than ${360}^{\circ }$.

(a) $reflex\angle DOB$
(b) $reflex\angle DOC$


Hence, required two reflex angles are
$reflex\angle DOB$ and $reflex\angle DOC$.
