Supplementary Angle Calculator | Find Supplementary Angles Easily
Calculate supplementary angles online with our easy-to-use tool. Enter an angle and instantly find its supplementary angle. Perfect for geometry and math calculations.
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: $$ Supplementary Angle = 180° - Angle $$
Visual Representation
Red line represents the input angle, and blue line represents its supplementary 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:
Example
If you have an angle of 60°, its supplementary angle is calculated as follows:
Therefore, the supplementary angle of 60° is 120°.
