Angles Around a Point

Angles around a point will always add up to 360 degrees.


The angles above all add to 360°

140° + 87° + 53° + 80°  = 360°

Because of this, if there is an unknown angle we can always find it.

 

Example: What is angle "c"?

to find angle c we take the sum of the known angles and take that from 360°


Sum of known angles = 110° + 75° + 50°  + 63°
Sum of Known angles = 298°
Angle c = 360° − 298°
Angle c = 62°
