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.
When adjacent angles add to , the two non-common rays form a straight angle, and the two angles are called a linear pair: The word supplementary is given when two angles add to 180o. This word is less specific than linear pair in that the angles do not have to be adjacent. Their measures just have to add to 180o.
