Angles Around a Point

We can also use our

knowledge of angles to find

missing angles around a

point.

There are 360˚in a full

turn.

All of the angles around a

4 point will add up to this.

How to find missing angles around a point

I know that there are 360˚ in a

full turn.

I can see that there is already

an angle of 128˚ and 141˚.

128 + 141 = 269

To find the missing angle I need

to find the difference between

269 and 360.

360 – 269 = 91

Angle x = 91˚

Why don’t you try?

Remember that all of

the angles should add

up to 360˚.

Add together the

angles you already

have.

Then find the

difference between 360.
