# Maths KS3: Angles

Angles feature in our lives in ways which we normally don't notice, even our movements.

Sanjeev Kohli takes us on a trip to the hairdresser's where a stylist, Sharz Din, explains that angles are important in his technical work.

We are shown how angles define a particular cut, the graduated bob.

The terminology of angles is used throughout in a practical way.

### Teacher Notes

This clip gives learners an insight into using angles in the workplace - in a surprising situation.

It can be used as a lesson on the terminology used in describing angles.

For many this will be revision but will show these terms being used in a practical way.

Learners could discuss other ways that angles feature in everyday life - in diverse ways such as in an aeroplane changing direction and in the movement of the hands of an analogue clock.

Extend activity into calculating the missing angle in a diagram, measuring angles, making a scale drawing involving an angle.

Research the use of angles in 3-figure directional bearings and consider why zeros are included when the angle is less than 100 degrees.
