# Find the number of right angles turned through by the hour hand of a clock when it goes from

(a) 3 to 6

(b) 2 to 8

(c) 5 to 11

(d) 10 to 1

(e) 12 to 9

(f) 12 to 6

**Solution:**

We will be using the concepts of revolution and clockwise rotation to solve this.

**(a)** 3 to 6 - The hour hand turns through 1 right angle starting from 3 to 6.

**(b)** 2 to 8 - The hour hand turns through 2 right angles starting from 2 to 8.

**(c)** 5 to 11- The hour hand turns through 2 right angles starting from 5 to 11.

**(d)** 10 to 1 - The hour hand turns through 1 right angle starting from 10 to 1.

**(e)** 12 to 9 - The hour hand turns through 3 right angles starting from 12 to 9.

**(f)** 12 to 6 - The hour hand turns through 2 right angles starting from 12 to 6.
