Question

Which counterclockwise rotation is equivalent to a clockwise rotation of 40°?

Answer 1

A whole turn is 360° so to turn 40° clockwise is equivalent to turn 320° counterclockwise.

Answer 2

The total angle around a point is 360 degrees

If we have a clockwise rotation of 40 degrees, then the converse of this must me done in the counter clockwise direction in order to achieve the same angle

To do the converse we should move a total of 360 - 40 degrees in the counter clockwise direction because the total is 360 degrees

Converse move = 360 - 40 = 320 degrees

So, a 320 degree counter clockwise move would be equal to a clockwise move of 40 degrees
