# Linear Pair

These lessons cover High School Math based on the topics required for the Regents Exam conducted by NYSED.
Here, we look at linear pairs.

What are Linear Pairs?
Linear Pairs are two adjacent angles whose non common sides form a straight line. Linear pairs are supplementary angles i.e. they add up to 180°.

The following diagrams show examples of Linear Pairs. Scroll down the page for more examples and solutions on how to identify and use Linear Pairs. Linear Pairs and Vertical Angles
This video describes linear pairs and vertical angles. It also solves a few example problems to help you understand these concepts better.
