## Types of angles

Manipulate points A, B or C below to discover the different types of angles and what degrees define them.
Note each of the different angles in your workbook and their definitions.

*Can you think of any others?*## Watch this video to remind you of all the different angles.

Check the angles you notes in your workbook - did you get them all? Add any you might have missed.

## Calculating angles

Can you calculate the angle using the protractor?

***Remember to match the centre of the protractor with the vertex of the angle (match blue dots) and zero the line (with red dot) on one line - measuring the angle to the other line.*Complete 10 different examples below and write the angle and the type of angle for each in your workbook. Don't forget -*the reflex angle is calculated by subtracting the acute angle from 360*
