To use the calculator, the user simply inputs the length of the three sides of the triangle and the calculator will use the law of cosines to determine the angles. The results are displayed in degrees and can be used to solve problems in geometry, engineering, and other fields.

The law of cosines:

,

thus

For degenerate triangle, where side lengths violate the following inequalities

,

,

,

the results will be zeroes.
