How do you identify a linear pair?

A linear pair can be defined as two adjacent angles that add up to 180° or two angles which when combined together form a line or a straight angle. Three angles can be supplementary, but not necessarily adjacent. For instance, angles in any triangle add up to 180° but they don't form a linear pair.

What are the characteristics of a linear pair?

A linear pair can be defined as two adjacent angles that add up to 180° or two angles which when combined together form a line or a straight angle. Three angles can be supplementary, but not necessarily adjacent. For instance, angles in any triangle add up to 180° but they don't form a linear pair.

How do linear pairs work in geometry?

In geometry, a linear pair of angles is a pair of adjacent angles formed when two lines intersect each other. Adjacent angles are formed when two angles have a common vertex and a common arm but do not overlap. The linear pair of angles are always supplementary as they form on a straight line.

What is the sum of the measures of a linear pair?

The sum of two angles in a linear pair is always 180°. All linear pairs of angles are adjacent angles but all adjacent angles are not linear pairs. Linear pair of angles share a common vertex and a common arm between them. They always form on a straight line. They can be considered as two parts of a 180-degree angle or a straight angle.
