(a) if a hand clock Starts at 12 and makes \frac{1}{2}of a revolution, clockwise, i.e two right angles, it reaches 6.
(b) if a hand clock Starts at 2 and makes \frac{1}{2}of a revolution, clockwise, i.e two right angles, it reaches 8.
(c) if a hand clock Starts at 5 and makes \frac{1}{4}of a revolution, clockwise, i.e one right angle, it reaches 8.
