Question

which are properties of rotations? check all that apply. rotations are always counterclockwise. rotations preserve size. rotations of 360° map a figure to itself. lines connecting corresponding points on the pre - image and image are parallel. lines connecting corresponding points on the pre - image and image have equal length. lines connecting the center of rotation to the pre - image and the corresponding point on the image have equal length.

Explanation:

Rotations can be clock - wise or counter - clockwise. Rotations are rigid motions that preserve size and shape. A 360 - degree rotation maps a figure onto itself. Lines connecting corresponding points on pre - image and image are not parallel. Lines connecting corresponding points on pre - image and image do not necessarily have equal length. Lines connecting the center of rotation to the pre - image and corresponding point on the image have equal length as rotation is a transformation about a fixed point (center of rotation) and distances from the center of rotation to points on the figure remain the same.

Answer:

Rotations preserve size.
Rotations of 360° map a figure to itself.
Lines connecting the center of rotation to the pre - image and the corresponding point on the image have equal length.
