Question

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

Explanation:

Step1: Determine the number of identical parts.

The figure has 4 identical - looking parts.

Step2: Calculate the angle of rotation.

The full - circle is 360°. To find the smallest rotation angle that maps the figure onto itself, we divide 360° by the number of identical parts. So, the angle $\theta=\frac{360^{\circ}}{4}=90^{\circ}$.

Answer:

90
