Where will the hour hand of a clock stop, if it starts
(a) from 6 and turns through 1 right angle?
(b) from 8 and turns through 2 right angles?
(c) from 10 and turns through 3 right angles?
(d) from 7 and turns through 2 straight angles?
As we know one complete revolution is of 360° which is consist of 4 right angles.
By looking at the clock we can tell;
(a) If the hour hand of the clock start from 6 and make 1 right angle then it will stop at 9.
(b) If the hour hand of the clock start from 8 and make 2 right angles then it will stop at 2.
(c) If the hour hand of the clock start from 10 and make 3 right angles then it will stop at 7.
(d) If the hour hand of the clock start from 7 and make 2 straight angles then it will stop at 7.
