Question
What part of a revolution have you turned through if you stand facing south and turn clockwise to face east?
Solution
If we revolve one complete round in either clockwise or anti-clockwise direction, then we will revolve by 360º and the two adjacent directions will be at 90º or `1/4` of a complete revolution away from each other.
If we start facing South and turn clockwise to face east, then we have to make `3/4` of a revolution.
