Question

What part of a revolution have you turned through if you stand facing a) North and turn clockwise to face East. b) East and turn clockwise to face South. c) East and turn clockwise to face West.​

Answer 1

Answer:

a)Here, the turn from east to the south is one right angle, from south to west is one right angle and from west to the north is one right angle.

so, the turn from east to the north is three right angles. 3/4 of a revolution is required to turn from east to north

(b) The turn from the south to the east is three right angles. i.e. from south to west, one right angle, from west to north is one right angle, and from north to east is one right angle. 3/4 of a revolution is required to turn from the south to the east.

(c) The turns from west to east, so two right angles. 1/2 of a revolution is required from west to east.
