Question 3.
Which direction will you face if you start facing
AP 6th Class Maths 5th Chapter Understanding Elementary Shapes Exercise 5.2 Solutions Img 11
a) ast and make \(\frac { 1 }{ 2 }\) of a revolution clockwise?
b) east and make 1\(\frac { 1 }{ 2 }\) of a revolution clockwise ?
c) west and make \(\frac { 3 }{ 4 }\) of a revolution anti-clockwise ?
d) south and make one full revolution?
(Should we specify clockwise or anticlockwise for this last question? Why not?)
Solution:
AP 6th Class Maths 5th Chapter Understanding Elementary Shapes Exercise 5.2 Solutions Img 12
Taking one full revolution we will reach back to the starting position.
Therefore it make no difference whether we turn clockwise or anticlockwise.

Question 4.
What part of a revolution have you turned through if you stand facing
a) east and turn clockwise to face north?
Solution:
If we start from east and reach at north (turning clockwise) \(\frac { 3 }{ 4 }\) of a revolution is required.
