Answer:
360°
Step-by-step explanation:
Any figure can map onto itself by rotating it 360°.
The angle of rotation that is an angle of rotational symmetry for all figures is 360°.
Rotational symmetry is also referred to as the radial symmetry. It simply refers to the property of a shape after a rotation has been done.
It should be noted that a shape has a rotational symmetry when it can be rotated between the angles of 0° and 360°. Therefore, the angle of rotation that is an angle of rotational symmetry for all figures is 360°.
