प्रश्न
What part of a revolution have you turned through if you stand facing west and turn clockwise to face east?
उत्तर
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 West and turn clockwise to face East, then we have to make `1/2` of a revolution.
