## How many right angles are there from north to south?

An angle of 0° corresponds to north, a 90° angle corresponds to east, a **180**° angle to south, 270° to west and finally, an angle of 360° (that is, a full circle) corresponds again to north.

## Where will the hand of a clock stop if it starts at 12 and makes 1/2 of a revolution clockwise?

Explanation: In one complete revolution, the clock hand moves 360° or 12 hours. A) If the clock hand starts at 12 and makes 1/2 of a revolution, it would stop after 6 hours, that is, at **6 o’clock**.

## Where will the hour hand of a clock stop if it starts from 7 and turns through 2 straight angles?

iv) if the hour hand starts from 7 and turns through two straight angles it will reach 7 because two straight angles make **four right angles**.

## Where will the hour hand of a clock stop if it starts from 8 and turns through 2 right angles?

If the hour hand of a clock starts from 8 and turns through 2 right angles, then it will **stop at 2**.
