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 the number of equal - parts

The basketball image has 4 equal - parts created by the lines.

Step2: Calculate the angle of rotation

The total angle of a full rotation is 360°. To find the smallest angle of rotation for rotational symmetry, we divide 360° by the number of equal - parts. So, the angle of rotation $\theta=\frac{360}{4}$.

Step3: Solve the division

$\frac{360}{4}=90$.

Answer:

90
