Angle Addition Postulate

Angle Type - Linear Pair

Recall that two angles whose measures add up to 180° are called supplementary angles.

One type of supplementary angle pair is called a linear pair. A linear pair is a pair of adjacent angles whose non-common sides are opposite rays.

You will prove this theorem in an exercise in this lesson.You can use the Linear Pair Theorem, as well as the Segment Addition Postulate and Angle Addition Postulate, to find missing values in expressions for segment lengths and angle measures
