No, but the can be adjacent angles. It is mathematically valid even though it serves no point.

A linear pair would be two angles that form a straight angle of 180 degrees.
Supplementary angles
Supplementary Angles total 180o. A straight line is theoretically an angle of 180o. Draw a straight line (ruler) and draw another straight line from anywhere you like on it and at any angle you like. You have created a pair of supplementary angles!
Linear Pair
It is to bisect an angle into equal angles usually done with a pair of compasses and a straight edge
they are called supplementary angles. a straight line has 180 degrees each side and two adjacent angles forming 180 degrees are called supplementary angles.
180 degrees a straight angle.
do not they are 2 angle with a common side and vertics that do not otherwise overlap.
