What is the definition of supplementary angles?

Supplementary angles are defined as two angles whose measures add up to exactly 180 degrees. This definition is fundamental in geometry and is often encountered in different problems involving angle relationships. For example, when two angles form a straight line, they are classified as supplementary because the total measurement around the line is 180 degrees.

The concept of supplementary angles has practical applications in various geometric constructions and proofs, as well as in solving problems where angle measures are unknown. Understanding this concept is crucial for recognizing angle relationships and solving equations involving angles in both theoretical and applied mathematics contexts.
