Question

Based on what you know about rotations, what do you think the mapping rule is for a rotation of 270 degrees clockwise? Explain.

Answer 1

There are 360 degrees in one revolution.x
A 270 dedgree clockwise rotation is the same as a 90 degrees counterclockwise rotation
(x,y) maps to (-y,x)

Answer 2

There are 360 degrees in one revolution, so a 270-degree clockwise rotation would be the same as a 90-degree counterclockwise rotation. Therefore, the rule would be to map (x, y) to (–y, x).
