Complementary adjacent angles are always adjacent (meaning they share a common vertex) and their non-shared sides form a line. In other words, they form a straight line! Supplementary AnglesSupplementary angles always add up to 180 degrees—but what happens when one or both of the angles is ...
Supplementary angles are two angles which form a straight line and whose measures add up to 180°. A trick that you should know is that complementary angles have special trigonometric properties: For any two complementary angles A and B, sinA=cosB and cosA=sinB. Here is an...

SMART Board E-Lessons for Geometry: Complementary and Supplementary Angles
Complementary angles: Two angles that add up to 90 degrees. Supplementary angles: Two angles that add up to 180 degrees. Vertical angles: A pair of opposite angles formed by the intersection of two lines. Vertical angles are equal in measure. ...
Complementary Angles:Complementary angles are a pair of angles whose measures add up to 90 degrees. Diameter:(1) In plane geometry, the diameter is the straight-line distance between two points opposite one another across the center of a circle. (2) In solid geometry, the diameter is the st...
