Chapter 12, Problem 15CT

To determine

To Draw:The polygon and any lines of symmetry.

Explanation of Solution

Given information:If the polygon has rotational symmetry and each angle of rotation that produce rotational symmetry.

Description: from the given polygon and any lines of symmetry.If the polygon has rotational symmetry and there are parallel to each other .Now if I rotate ${180}^{\circ }$ any line of the polygon there is no change to each’

So the angle of the rotation is ${180}^{\circ }$ .

There is no particular direction for rotation of the given polygon.

So the direction of rotation is clockwise or anti clockwise.

The figure of the polygon,
