The sum of the measure of the supplementary angle is _____.

The sum of the measures of supplementary angles is always 180 degrees. This means that if you have one angle, you can find its supplementary angle by subtracting it from 180 degrees.

Understanding Supplementary Angles

Supplementary angles are two angles that add up to 180 degrees. For example:

• If one angle measures 70 degrees, its supplementary angle would be 110 degrees (180 - 70 = 110).
• If one angle is 90 degrees, its supplementary angle is also 90 degrees (90 + 90 = 180).

Why It Matters

Knowing about supplementary angles is useful in various fields, including geometry, architecture, and design. It helps in solving problems related to angles in different shapes and structures.
