Question

rotational symmetry does the figure have rotational symmetry? if so, state the degree measure of the angle of rotation. yes no 45° 90° 30° 180°

Explanation:

Step1: Define rotational symmetry

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

Step2: Analyze the cross - shaped figure

The cross - shaped figure can be rotated by 90°, 180°, 270° and still look the same. The smallest non - zero angle of rotation for which it looks the same is 90°.

Answer:

YES, 90°
