Based on what you know about rotations, what do you think the mapping rule is for a rotation of 270 degrees clockwise? Explain.
A rotation of 270 degrees clockwise is equivalent to a 90-degree counterclockwise rotation. Since there are 360 degrees in a full circle, 360 - 270 = 90. Therefore, the mapping rule for a 270-degree clockwise rotation is (x, y) → (–y, x).
