Question

the figure below has rotational symmetry. ° is the smallest possible rotation that results in the figure being mapped onto itself.

Explanation:

Step1: Count congruent parts

The figure has 12 congruent - looking parts.

Step2: Calculate rotation angle

The total angle of a full - rotation is 360°. To find the smallest rotation that maps the figure onto itself, divide 360° by the number of congruent parts. So, $\frac{360}{12}=30$.

Answer:

30
