Question

which are not changed after a rotation? check all that apply. angle measures orientation size shape position of center of rotation

Explanation:

Rotation is a rigid transformation. Rigid transformations preserve angle measures, size, and shape. The center of rotation is a fixed point during rotation, so its position doesn't change. Orientation (the way a figure is turned or arranged) can change after rotation. For example, a triangle rotated \(90^{\circ}\) will have a different orientation compared to its original position.

Answer:

angle measures, size, shape, position of center of rotation
