# What part of a revolution have you turned through if you stand facing

(a) east and turn clockwise to face north?

(b) south and turn clockwise to face east?

(c) west and turn clockwise to face east?

**Solution:**

We will be using the concepts of revolution and clockwise rotation to solve this.

(a) If we start from east and turn clockwise to face north,3/4 of a revolution is required, as seen in the image below.

(b) If we start from the south and turn clockwise to face east, 3/4 of a revolution is required.

(c) If we start from the west and turn clockwise to face east, 1/2 of a revolution is required.
