What part of a revolution have you turned through if you stand to face: (a) East and turn clockwise to face north? (b) South and turn clockwise to face east? (c) West and turn clockwise to face east?
Step 1: East and turn clockwise to face north.
One complete revolution has four right angles.
One revolution angle
The diagram of directions is shown below:
From the diagram, observe that the turning from east to north requires three right angles in a clockwise direction.
Thus, turning from east to north will be of a revolution.
Hence, the revolution is .
Step 2: South and turn clockwise to face east.
From the diagram, observe that the turning from south to the east requires three right angles in a clockwise direction. Thus, turning from the south to the east will of a revolution.
Hence, the revolution is .
Step 3: West and turn clockwise to face east.
From the diagram, observe that the turning from west to the east requires two right angles in a clockwise direction. Thus, turning from west to east will be of a revolution.
Hence, the revolution is .
Hence, the values of the revolutions are (a) (b) (c) .
