Question

which angle of rotation is an angle of rotational symmetry for all figures? 45° 90° 180° 360°

Explanation:

Step1: Define rotational symmetry

Rotational symmetry is when a figure looks the same after a rotation.

Step2: Analyze each option

45°, 90°, 180° are not for all figures. But a 360° rotation makes any figure coincide with itself.

Answer:

D. 360°
