trianglesolver
Find all the sides and angles of a triangle, if you know some of the sides and/or angles. (Uses the Law of Sines and Law of Cosines.)

What it is and what it does
Trianglesolver is a lightweight utility that applies trigonometric laws to compute missing sides and angles in a triangle when you provide at least three known values. It exports a single main function, solve(), that takes any combination of side lengths (a, b, c) and angles (A, B, C) as keyword arguments and returns all six values. The package follows standard geometric convention: lowercase letters denote sides, uppercase denote angles, and corresponding letters are opposite each other.
The package has no runtime dependencies and installs as a pure Python wheel, making it trivial to add to any project. All angles are in radians by default, but a degree constant is provided for easy conversion. It is intended for educational use and scientific applications where quick triangle calculations are needed.
Use it for
- Educational geometry or trigonometry exercises where students need to verify triangle solutions.
- Scientific simulations or engineering calculations requiring rapid triangle geometry resolution.
- Navigation or surveying applications where partial triangle measurements must be completed.
- Physics or mechanics problems involving triangular force diagrams or structural analysis.
