Question

rotational symmetry. has does not have

Explanation:

Step1: Recall rotation - symmetry definition

A shape has rotational symmetry if it can be rotated by an angle less than 360° and still look the same.

Step2: Analyze the given star - shaped figure

The given figure has 12 equal - length segments radiating from a central point. When rotated by an angle of $\frac{360^{\circ}}{12}=30^{\circ}$ (or multiples of 30°), it will coincide with its original position.

Answer:

has
