Calculate any angle values you need quickly and accurately with this tool.

## Angle Calculator

This calculator allows you to convert between degrees and radians, and also computes the sine, cosine, and tangent of the angle.

### How to Use:

- Select the type of angle (Degrees or Radians) from the dropdown menu.
- Enter the angle value in the input field.
- Click on the “Calculate” button to see the results.

### Calculation Explanation:

The calculator converts between degrees and radians using the following formulas:

**Radians to Degrees:**Degrees = Radians × (180 / π)**Degrees to Radians:**Radians = Degrees × (π / 180)

It also calculates the trigonometric values using JavaScript’s built-in Math functions:

**Sine:**Math.sin(angle_value)**Cosine:**Math.cos(angle_value)**Tangent:**Math.tan(angle_value)

### Limitations:

The calculator might show inaccuracies for very small or large values due to the inherent limitations of floating-point arithmetic in JavaScript. Angle values must be real numbers.

## Use Cases for This Calculator

### Determine Interior Angles of a Triangle

You can easily determine the interior angles of any triangle using an angle calculator. By inputting the measures of two angles, the calculator will automatically give you the measure of the third angle, ensuring your calculations are accurate and efficient.

### Calculate Angles in Right Triangles

If you’re working with right triangles, this angle calculator aids in finding the measures of the non-right angles when one angle is known. Just enter the known angle, and the calculator will provide the other angle measurement, making it a breeze to solve for unknowns.

### Convert Between Radians and Degrees

You might often need to switch between radians and degrees for various applications, and an angle calculator simplifies this process. Enter the angle measurement in one format, and the calculator will instantly convert it to the other, saving you time and reducing errors.

### Calculate Angles of Polygons

When you want to find the interior angles of polygons, this calculator proves handy. Simply input the number of sides, and it will compute the total interior angles and provide the measure of each angle, empowering you to work effectively on geometric projects.

### Determine Complementary Angles

Understanding complementary angles can be tricky, but an angle calculator makes it straightforward. Enter one angle, and the calculator will quickly show you its complementary angle, which always adds up to 90 degrees, ensuring your calculations are spot on.

### Calculate Supplementary Angles

If you’re interested in supplementary angles, you can easily find them using the calculator. Just input the measure of one angle, and it will calculate the corresponding angle that adds up to 180 degrees, providing clarity in your geometric tasks.

### Find Angles in Trigonometric Functions

When working with trigonometric functions like sine, cosine, or tangent, an angle calculator is essential for finding angles based on given ratios. Simply input the values, and it will provide the angle measurements directly, allowing you to focus on other aspects of your calculations.

### Visualize Angles with Graphing Tools
