Calculate the Other Angle in a Linear Pair

What is a Linear Pair?

A linear pair is a pair of adjacent angles formed when two lines intersect. The angles in a linear pair are supplementary, meaning their measures add up to 180 degrees. Linear pairs are commonly encountered in geometry and are used to solve various problems involving angles and lines.

Formula

The formula to calculate the other angle in a linear pair is:

\[ A_2 = 180^\circ - A_1 \]

Where:

Example

Let's say the first angle (\( A_1 \)) is 70 degrees. Using the formula:

\[ A_2 = 180^\circ - 70^\circ = 110^\circ \]

So, the second angle (\( A_2 \)) is 110 degrees.
