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

Explanation

To find the number of right angles turned through by the hour hand of a clock for each specified time interval, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Clock Movement**:
- A complete circle of the clock is 360 degrees.
- The hour hand completes one full circle (360 degrees) in 12 hours.
- Therefore, the hour hand moves 30 degrees for each hour (360 degrees / 12 hours = 30 degrees/hour).
