If m ∠ 1 = (6x+2) °, and m ∠ 2 = (4x-12) °, find So the measure of angle DBC would be equal to 90 degrees. Complementary Angles but not Adjacent. Angle Pair Matching Activity Vocabulary Diagram Facts Same Side Interior Angles (Consecutive) Supplementary Alternate Interior Angles Complementary Linear Pair Corresponding Angles Alternate Exterior Angles Vertical Angles Same Side Exterior Angles (Consecutive) The angles add up to 180 °. An example of adjacent complementary angles is given below: Remember that perpendicular means forming a right angle. If two angles make up 90 o by adding up then it is called complementary angles. For example, a \(15^{\circ}\) angle and a \(75^{\circ}\) angle are complementary. A linear pair is a pair of adjacent angles whose noncommon sides are opposite rays. What Are Complementary Angles.
