3 knowns → everything, drawn to scale

📐 Triangle Solver

Enter any valid trio — three sides, two sides & an angle, or one side & two angles — and get all sides, angles, area, radii… with the triangle drawn to true scale. The ambiguous SSA case shows both solutions.

Conventions: side a faces angle A (at vertex A), b faces B, c faces C; angles in degrees. SSA can have 0, 1 or 2 triangles — when the given side is shorter than the height, no triangle exists. Area by Heron's formula; R = abc/4S; r = S/p.
