Define adjacent angles, linear pair of angles. What is the sum of the linear pair of angles?

Adjacent Angles: Two angles are called adjacent angles if they have a common vertex and a common arm (side), but no common interior points. In other words, they share a side and a vertex but are not overlapping.

Linear Pair of Angles: A linear pair of angles consists of two adjacent angles whose non-common sides form a straight line. This means that the two angles in a linear pair are supplementary.

Sum of a Linear Pair of Angles: The sum of the angles in a linear pair is always 180 degrees. This is because the two angles form a straight line, and the angle of a straight line is always 180 degrees.

So, the sum of the linear pair of angles is 180 degrees.
