Question

Which angles form a linear pair?

Answer 1

Explanation:

The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

Answer 2

Adjacent angles formed by two intersecting lines form a linear pair.

Explanation:

A linear pair of angles is formed when two lines intersect. A linear pair of angles must add up to 180 degrees.

If two angles are adjacent angles that are formed by two intersecting lines, then they are called linear.
