Find the number of right angles turned through by the hour hand of a clock when it goes from
12 to 6

Answer

To solve the problem of how many right angles the hour hand of a clock turns through when it moves from 12 to 6, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Clock Positions**:
- The clock has 12 positions (1 to 12). Each hour represents a position on the clock.

2. **Identify the Starting and Ending Positions**:
- The hour hand starts at 12 and moves to 6.

3. **Calculate the Total Movement**:
- From 12 to 6, the hour hand moves through 6 positions (12 to 1, 1 to 2, 2 to 3, 3 to 4, 4 to 5, and finally 5 to 6).

4. **Determine the Right Angles**:
- Each hour represents a 30-degree movement (360 degrees divided by 12 hours = 30 degrees per hour).
- The hour hand moves from 12 to 6, which is a total of 6 hours.
- Total degrees turned = 6 hours × 30 degrees/hour = 180 degrees.

5. **Calculate the Number of Right Angles**:
- A right angle is 90 degrees.
- To find the number of right angles in 180 degrees, divide 180 degrees by 90 degrees.
- Number of right angles = 180 degrees ÷ 90 degrees = 2.

### Final Answer:
The hour hand of the clock turns through **2 right angles** when it moves from 12 to 6.
