Heron's Formula Calculator
Calculate the area of any triangle using Heron's formula by entering the lengths of all three sides.
About Heron's Formula
Heron's formula (also known as Hero's formula) is used to calculate the area of a triangle when you know the lengths of all three sides. It's particularly useful when you can't easily find the height of the triangle.
How to Use
- Enter the length of side A
- Enter the length of side B
- Enter the length of side C
- Click "Calculate Area" to see the results
Understanding the Results
The calculator provides:
- The area of the triangle
- Step-by-step solution using Heron's formula
- Triangle properties including angles and type
- Validation of the triangle inequality theorem
The Formula
A = √(s(s-a)(s-b)(s-c))
where s = (a + b + c)/2 is the semi-perimeter of the triangle
