Description

From the listing uploaded by “lacostetm”.

This application is an universal calculator for triangles. When you give three parameters (sides or angles), this tool computes the remaining parameters and the area of triangle. The triangle thus determined is displayed with its height. It works with any right or non-right triangle, including the ambiguous case of the law of sines (the two solutions are given). Support angles in degrees, radians and grads. Useful for trigonometry, roof computations, math, homework or CNC. Feel free to email developer to request features, localizations, or anything else ! Simple and effective, and available for free !
