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, so they preserve size. A 360° rotation brings a figure back to its original position. Lines connecting the center of rotation to pre - image and image corresponding points have equal length as the distance from the center of rotation to a point remains the same during rotation. Lines connecting corresponding points on pre - image and image are not parallel in general and do not have equal length in general.

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.
