What are supplementary angles? Supplementary angles and complementary angles are angles that add up to a specific degree measure, and in today's video we are talking about the former. Two angles are supplementary if they add up to 180 degrees. Supplementary angles, when placed adjacent to each other, form a straight line, a 180 degree angle. Do note however that supplementary angles do not have to be adjacent to each other, they need only to have an angle measure sum of 180 degrees. Adjacent supplementary angles are not literally a linear pair, but they look very similar to linear pairs, the only difference being that a linear pair occurs when two straight lines intersect and adjacent supplementary angles are just that, not intersecting lines. If that is unclear ask questions in the comments!
I hope you find this video helpful, and be sure to ask any questions down in the comments!
