**Angle**

An angle is formed when two straight lines meet at a point.

**For example,**

Here, line A meets line B at point C. It makes an angle there.

An angle is represented by the symbol ‘**∠**’ and is measured in ‘degrees or **°**.

**Right angle**

When two straight lines meet each other, they form a right angle.

It is represented by a small square at the point where the lines meet.

**Example,**

The measure of a right angle is 90°.

**Quarter Turn**

Turn from the yellow line to the orange line is a quarter turn.

One-quarter turn is the same as one right angle.

**Half turn**

Turning the from yellow line to the green line is a half turn.

Two quarter turns or two right angles make one-half turn.

**Three quarter Turn**

Turning from the yellow line to the blue line is called the three-quarter turn.

Three right angles make a three-quarter turn.

**Clockwise and Anti-clockwise **

**Clockwise**

Clockwise means turning the same way the hands on a clock.

**Anti-clock wise**

Anti-clockwise means turning the opposite way in the directions of the hands on a clock.

**Let’s try a question.**

If the hour hand of the clock takes a clockwise quarter turn, what time will be shown by the clock?

**Solution**:

The hour hand will be at 6.
