What is a linear pair of angles?

Back

A linear pair of angles consists of two adjacent angles formed when two lines intersect. The sum of the angles in a linear pair is always 180 degrees.

If angle 3 is 55 degrees, what is the measure of angle 2 if they are a linear pair?

Back

Angle 2 is 125 degrees because 180 - 55 = 125.
