Triangle Solver Calculator
Enter known sides and angles to solve for the remaining values, including area and perimeter.
Formulas Used:
Law of Sines:
a / sin(A) = b / sin(B) = c / sin(C)
Law of Cosines:
c² = a² + b² − 2ab × cos(C)
Area (Heron’s Formula):
s = (a + b + c) / 2
Area = √[s(s−a)(s−b)(s−c)]
This calculator can handle SSS, SAS, ASA, AAS, and SSA configurations to find all triangle properties.
