1. 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.
2 180
3
270
All of the angles around a
4 point will add up to this.
4 360
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.
