Question

this image has rotational symmetry. what is the smallest number of degrees you need to rotate the image for it to look the same?

Explanation:

Step1: Analyze rotational symmetry

The image has a two - fold rotational symmetry.

Step2: Calculate rotation angle

A full rotation is 360 degrees. For a two - fold symmetry, $\frac{360}{2}=180$ degrees.

Answer:

180
