What is Triangle?
Triangle solving uses trigonometric laws to find unknown measurements. Supports SSS, SAS, ASA, AAS, and SSA (ambiguous case) inputs.
How it works
We apply the appropriate law (sine or cosine) based on the known values, solve for unknowns incrementally, and flag the ambiguous SSA case.
