Question

How much of a revolution have you turned through if you stand facing
A. North and turn clockwise to face west? B. East and turn anti-clockwise to face west?
C. South and turn anti-clockwise to face east?​

Answer 1

Answer:

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.

hence, 3/4th of a revolution is required to turn from east to north.

(ii) here, 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.

hence, 3/4th of a revolution is required to turn from south to east.

(iii) here, the turn from west to east so two right angles.

hence, 1/2 of a revolution is required from west to east.
