What are Supplementary Angles?
Two angles are supplementary if they add up to 180°. Supplementary angles, when placed adjacent to each other, form a straight line, a 180° 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.
The following diagrams show examples of supplementary angles. Scroll down the page for more examples and solutions for supplementary angles.
