Lesson Summary. Supplementary angles are any two angles whose measures sum to 180 degrees. Supplementary angle pairs will either be two right angles (both 90 degrees) or be one acute angle and one obtuse angle. If two angles are both supplementary to the same angle, then the two angles are of equal measure.
Two angles are said to be adjacent angles if they have a common vertex and a common arm. If two supplementary angles are adjacent to each other, they are called a linear pair and form a straight line. In real life, supplementary angles are seen in many places.
