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: Identify rotational symmetry

The image has 2 - fold rotational symmetry.

Step2: Calculate rotation angle

The full - circle is 360 degrees. For 2 - fold symmetry, $\frac{360}{2}=180$ degrees.

Answer:

180
