Triangle Solver automatically solves any defined triangle. Simply insert the information you know about a triangle, and Triangle Solver tells you what you don't know. Triangle solver is not simply a calculator - Its intelligent. As well as knowing formulas it also knows when to employ them. This makes Triangle Solver easy to use and invaluable even for a math novice.

Triangle Solver can solve triangles defined by SSS, SAS, ASA, or even solve both solutions for ambiguous situations of SSA. Basically, if a triangle has a solution, Triangle Solver can find it. Even if the triangle has no solution, Triangle solver will tell you why.
