Suppose we are at 12,

And we rotate right angle

Right angle turns in a clock - Part 2

So, we will be at 3

  Since right angle makes 1/4 th of the complete rotation.

  Hours rotated in right angle = 12/4

= 3

 

If we go from 3 to 9,

Right angle turns in a clock - Part 3

 

We have turned 1/2 revolution

i.e. 2 × 1/4 revolution

i.e. 2 right angles

 

So, in a clock

12 hours = 1 revolution

1 hour = 1/12 revolution

3 hours = 3/12 = 1/4 revolution

6 hours = 6/12 = 1/2 revolution

 

So,

  Full revolution  = 12 hours

  Right angle = 3 hours

  Straight angle = 6 hours
