Triangle Angle Calculator
The Triangle Angle Calculator is a tool that calculates the angles of a triangle given the length of its sides.
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:
For degenerate triangle, where side lengths violate the following inequalities
the results will be zeroes.
