Point A is on the y-axis. Describe all possible locations of image A′ for rotations of 90°, 180°, and 270°. Include the origin as a possible location for A.


Complete the answer.

If A is at the origin, A′ for any rotation about the origin
(select)
at the origin. Otherwise, A′ is on the x-axis for
° and 270° rotations and on the y-axis for a
° rotation.
