Supplementary angles are two angles that will always add up to 180 degrees. Let's say that we have an acute angle that is 80 degrees and an obtuse angle which is 100 degrees. If we add the two angles together, we get a supplementary angle. Therefore, supplementary angles are very easy to understand. For more details about supplementary angles, please watch the following video.
