Decide whether each of the images has rotational symmetry re

Decide whether each of the images has rotational symmetry, reflectional symmetry, both, or neither. If it has rotational symmetry, solve for the angle of rotation. If it has reflectional symmetry, state the axis of symmetry or draw it on the image. It is possible there is more than one axis of reflection.

Solution

There is no partial rotational symmetry. This image has only 360° symmetry. Image remains same after the rotation of 360°. So angle of rotation is 360°.

Now, there is one reflection axis is vertical axis. It is symmetric about vertical axis or y-axis.
