If a ray lies between two sides of an angle in the plane of the angle, then the sum of the measure of the two smaller angles is equal to the measure of the larger side
|
Angle Addition Theorem
|
|
|
If the exterior sides of two angles are opposite rays, the angles are supplementary
|
Supplementary Angle Theorem
