Question

1. what do you call two angles whose sum is 90 degrees? linear pair adjacent angles complementary angles supplementary angles

Explanation:

• A linear pair of angles is a pair of adjacent angles whose non - common sides are opposite rays and their sum is \(180^{\circ}\).
• Adjacent angles are two angles that have a common vertex and a common side but no common interior points. Their sum is not necessarily \(90^{\circ}\).
• Complementary angles are defined as two angles whose sum is \(90^{\circ}\).
• Supplementary angles are two angles whose sum is \(180^{\circ}\).

Answer:

C. Complementary angles
