What are supplementary angles

The video tutorial explains supplementary angles, which are two angles whose measures add up to 180 degrees. It introduces the concept of opposite rays and how they form lines, leading to the creation of angles. The tutorial distinguishes between supplementary and adjacent angles, emphasizing that while adjacent angles can be supplementary, they don't have to be. It also covers linear pairs, which are two adjacent angles formed by opposite rays that are always supplementary. The video concludes by reinforcing the understanding that while all linear pairs are supplementary, not all supplementary angles are linear pairs.
