Question

Arun turns a right angle four times. This means that he rotated it by ___ degrees and it is called a ___ angle.

• A. 270${}^{\circ }$, Reflex angle
• B. 180${}^{\circ }$ , Straight angle
• C. 360${}^{\circ }$, Whole angle
• D. 91${}^{\circ }$ , Obtuse angle

Answer 1

The correct option is C

360${}^{\circ }$, Whole angle

Arun turns a right angle 4 times. Hence, the total measure of the angle is 4 $\times$ 90 = 360${}^{\circ }$. An angle which is equal to 360${}^{\circ }$ is called a whole angle.
