Results

Select a method and enter values to see results

Formulas & Methods

Law of Cosines: c² = a² + b² - 2ab·cos(C)
Law of Sines: a/sin(A) = b/sin(B) = c/sin(C)
Area (Heron's formula): A = √[s(s-a)(s-b)(s-c)], where s = (a+b+c)/2
Area (SAS): A = ½ab·sin(C)
Triangle Inequality: The sum of any two sides must be greater than the third side

Note: Calculations are provided as-is for educational and planning purposes. For critical applications, always verify results independently. SSA case may have ambiguous solutions.
