The formulary with the law of cosines can stay in the drawer: Trivice HD let you calculate the values of any given triangle.
The necessary parameters are:

The input is done completely without the keypad by using the graphical controllers on the edges and sides. The controller in the middle sets the fraction digits.

The calculation includes all angles and lengths as well as area, height and incircle and circumcircle. The result is also displayed graphically.

The last 10 calculations can be recalled from the history. The number of fraction digits for input and result can be defined in the settings. It is also possible to use fractions for the input, for example for inch values.
