## Angles and Turns

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.
