Understanding Supplementary Angles

A supplementary angle is the angle that, when added to the given angle, results in a sum of 180 degrees.

The formula to calculate the supplementary angle is: $$ Supplementary Angle = 180° - Angle $$

Understanding Supplementary Angles

In geometry, two angles are supplementary if their sum is 180 degrees. If two angles are supplementary, one angle is said to be the supplement of the other. Supplementary angles are often found in linear pairs, where two angles share a common vertex and side, forming a straight line.

Formula

The formula to find the supplementary angle of a given angle \( \theta \) is:

$$ Supplementary Angle = 180° - heta $$

Example

If you have an angle of 60°, its supplementary angle is calculated as follows:

$$ Supplementary Angle = 180° - 60° = 120° $$

Therefore, the supplementary angle of 60° is 120°.
