Question

08 Multiple Choice

A figure is rotated 90° clockwise, then 270° counterclockwise. Which single rotation is equivalent to this?

Answer 1

180 degrees.

Explanation:

If you start at 0 degrees and move 90 degrees clockwise, you subtract (clockwise is subtracting) 90 degrees to 0 degrees which is 90 degrees. Moving it 270 degrees counterclockwise means that you are adding 270 degrees. -90+270=180 degrees.
