Answer:
A figure has rotational symmetry if it can be rotated by an angle between 0° and 360° so that the image coincides with the preimage.
The angle of rotational symmetry is the smallest angle for which the figure can be rotated to coincide with itself.
The order of symmetry is the number of times the figure coincides with itself as its rotates through 360° .
