Angles Around a Point
Angles around a point will always add up to 360 degrees
Example: the angles above all add to 360°
53° + 80° + 140° + 87° = 360°
Because of this we can sometimes find an unknown angle.
Example: What is angle "c"?
To find angle c we take the sum of the known angles and subtract that from 360°
| Sum of known angles | = 110° + 75° + 50° + 63° | |
| = 298° | ||
| Angle c | = 360° − 298° | |
| = 62° |
