Question
How many right angles do you make if you start facing north and turn anti-clockwise to the east?
Solution
If we revolve one complete round in either clockwise or anti-clockwise direction, then we will revolve by 360º or 4 right angles and the two adjacent directions will be at 90º or 1 right angle away from each other.
If we start facing North and turn anti-clockwise to East, then we make 3 right angles.
