Complementary angles are two angles with a sum of 90Âº. Supplementary angles are two angles with a sum of 180Âº. Vertical angles are two angles whose sides form two pairs of opposite rays. We can think of these as opposite angles formed by an X. The Lesson:
Another example: When we add up the Interior Angle and Exterior Angle we get a straight line 180Â°. They are Supplementary Angles. Exterior Angles of Polygons Interior Angles Interior Angles of Polygons Supplementary Angles Angles On a Straight Line Straight Angle Degrees (Angle) Geometry Index.
