Using the Angles Calculator

This guide is designed to help you effectively utilize the Angles Calculator, which computes various angle-related values and trigonometric functions based on your input. Follow the steps below to perform calculations efficiently.

Step 1: Select the Angle Type

Selecting the correct unit for your angle measurement is crucial as it affects all subsequent calculations. You have two options to choose from:

  • Degrees: Choose this if your angle is measured in degrees.
  • Radians: Choose this if your angle is measured in radians.

Step 2: Enter the Angle Value

Once you have selected the angle type, enter the numerical value of the angle into the designated input field labeled “Angle Value”.

  • Ensure that the value falls within the range of -360 to 360.
  • You can specify an angle to two decimal places.

Step 3: Specify the Side Length

This step is necessary if you wish to perform trigonometric calculations involving a side of a triangle. Input the side length in the designated field labeled “Side Length (for trigonometric calculations)”.

  • The side length must be greater than 0.
  • Specify the length to two decimal places if needed.

Step 4: Review the Calculated Results

After entering the required values, review the results generated by the calculator. The following outputs will be displayed:

  • Converted Angle: Shows the angle converted to the alternate unit (degrees to radians or radians to degrees).
  • Normalized Angle (in degrees): Displays the equivalent angle within the 0-360° range.
  • Complementary Angle: Calculates the angle that, when added to the specified angle, equals 90 degrees or π/2 radians.
  • Supplementary Angle: Calculates the angle that, when added to the specified angle, equals 180 degrees or π radians.
  • Sine Value: Computes the sine of the specified angle.
  • Cosine Value: Computes the cosine of the specified angle.
  • Tangent Value: Computes the tangent of the specified angle.
  • Opposite Side Length: Calculates the length of the side opposite to the angle using the sine function.
  • Adjacent Side Length: Calculates the length of the side adjacent to the angle using the cosine function.
  • Hypotenuse Length: Displays the input side length, assuming it represents the hypotenuse of the triangle.

Following these steps will ensure you make the most of the Angles Calculator’s capabilities, enabling accurate and multifaceted angle and trigonometric computations.
