Triangle Calculator

Solving triangles: SSS, SAS, AAS, ASA

This solver handles all four triangle configurations using the Law of Cosines (for SSS and SAS) and the Law of Sines(for AAS and ASA). Given any valid combination of known sides and angles it calculates the remaining unknowns, the area (via Heron's formula), the perimeter, and the height to side c.
