Answer:
(a) We have, If we starts facing East and makes 1/2 of a revolution clockwise i.e. Two right angles, we will face West. (b) We have, If we starts facing East and makes \[1\frac{1}{2}\] of a revolution clockwise, i.e. One complete revolution and two right angles, we will face West. (c) We have, If we starts facing West and makes 3/4 of a revolution anti-clockwise. i.e. Three right angles, we will face North. (d) We have, If we starts facing South and makes one full revolution either clockwise or anti-clockwise, we will face South again. There is no need to specify clockwise or anti-clockwise for the last question because one full revolution will bring us back to the original position.
