In this activity, we will learn how to calculate angles in a full rotation.

Sometimes we call these angles around a point.

We know that all angles around a point add together to make a total of** 360°**

For example, below we can see that one of the angles around a point is 240°

The other, **a**, is unknown.

We can subtract the known angle from 360° to find the value of a.

360 - 240 = 120

**a = 120°**

Let's try an example question together.

**Example**

Calculate the other angle around this point.

**Answer**

Angle = 360° - 300° = 60°

Let's have a go at some questions now.
