(a) \(\frac{1}{2}\) or two right angles
(b) \(\frac{1}{4}\) or one right angle
(c) \(\frac{1}{4}\) or one right angle
(d) \(\frac{3}{4}\) or three right angles.
(e) \(\frac{3}{4}\)or three right angles.
(f) \(\frac{3}{4}\) or three right angles.
Which direction will you face if you start facing:
(a) East and make \(\frac{1}{2}\) of a revolution clockwise?
(b) East and make \(\frac{11}{2}\) of a revolution clockwise?
(c) West and makes \(\frac{3}{4}\) of a revolution, clockwise?
(d) South and make one full revolution?
(Should we specify clockwise or anti-clockwise for this last question? Why not?)
What part of a revolution have you turned through if you stand facing:
(a) East and turn clockwise to face north?
