Chapter 12.6, Problem 15E

To determine

To state: whether the figure has rotational symmetry not, and give the angle and direction of rotation.

Explanation of Solution

Given : the figureprovided in the question,

in this shown figure, it is shown that this figure have to be rotated ${30}^{\circ }$ in clockwise and also in counterclockwise to coincide itself. So the angle is ${30}^{\circ }$ in clockwise and counterclockwise direction.
