Triangle Area Calculator

How to Use the Triangle Area Calculator

Follow the steps below to calculate the area of triangle.

  1. Input the Values:
    • Side A (a): Enter the length of the first side of the triangle. This should be a positive number (e.g., 5).
    • Side B (b): Enter the length of the second side of the triangle. This should also be a positive number (e.g., 10).
    • Angle (θ): Enter the angle between the two sides. You can enter the angle in either degrees or radians. For example:
      • If in degrees: 30
      • If in radians: approximately 0.524 (for 30 degrees).
  2. Select the Unit:
    • Unit: Choose the unit for the angle from the dropdown menu:
      • Select Degrees if you entered the angle in degrees.
      • Select Radians if you entered the angle in radians.
  3. Calculate the Area:
    • Click the Calculate Area button.
    • The area of the triangle will be computed based on the provided inputs.
  4. View the Result:
    • The calculated area will be displayed below the input form. For example, if you entered 5 for Side A, 10 for Side B, and 30 degrees for the angle, it might show: “Triangle Area: 12.50”.

Example Scenario

  • Example Input:
    • Side A (a): 5
    • Side B (b): 10
    • Angle (θ): 30
    • Unit: Degrees
  • Expected Output:
    • After clicking “Calculate Area,” you should see: “Triangle Area: 12.50” (or a similar value depending on the specific calculation).
