Make sure students try clockwise and counterclockwise rotations. This is really old, but since I have stumbled upon here, I am adding the answer just in case someone else come looking. 180 degree CCW rotation. What is the coordinate for the image of point H (2, - 6) under a 90° clockwise rotation about the origin What is the image of the coordinate point (2, 3) if the rotation is 270 degrees Point Q (2, - 1) is rotated 90° clockwise about the origin.
