This tool helps you quickly find the supplementary angle of any given angle.

## How to Use the Supplementary Angles Calculator

This calculator helps you find the supplementary angle of a given angle. Supplementary angles are two angles whose sum is exactly 180 degrees.

- Enter the angle that you want to find the supplementary angle for in the input field.
- Click the “Calculate” button.
- The supplementary angle will be displayed in the “Supplementary Angle” field.

## How It Calculates the Results

The calculator subtracts the given angle from 180 degrees. The formula is:

*Supplementary Angle = 180 – Given Angle*

## Limitations

- The input angle must be a positive number between 1 and 179 degrees.
- Angles outside this range are not valid for supplementary angle calculations as they do not form a pair that adds up to 180 degrees.
