How to Use the Triangle Calculator?

1. Input Known Values
Start by entering the known values of your triangle into the appropriate input fields. The calculator accepts side lengths (a, b, c) and angle measurements (A, B, C). You need to provide at least three values, including at least one side length, to perform the calculations.

2. Side Lengths
Enter the lengths of the known sides in the “Side a,” “Side b,” and “Side c” fields. Use consistent units (e.g., centimeters, inches) for all measurements.

3. Angle Measurements
Input the known angle measurements in degrees in the “Angle A,” “Angle B,” and “Angle C” fields. Remember that the sum of all angles in a triangle must equal 180 degrees.

4. Calculate
Once you’ve entered the known values, click the “Calculate” button. The calculator will provide a comprehensive set of results, including:

  • All side lengths (a, b, c)
  • All angle measurements (A, B, C)
  • Triangle area
  • Triangle perimeter
  • Triangle type (equilateral, isosceles, scalene, or right-angled)

By following these steps and understanding the capabilities of the triangle calculator, users can efficiently solve a wide range of triangle-related problems and gain insights into the relationships between different triangle properties. Whether you’re a student learning geometry, a professional working on a complex project, or simply curious about triangles, this tool provides a user-friendly and accurate way to explore and solve triangle calculations.
