The formulary with the law of cosines can stay in the drawer: Trivice calculates the values of any given triangle.
The necessary parameters are:
- Three edges or
- Two edges and one angle or
- One edge and two angles
The input is made completely without the keypad by using the graphical controllers on the corners and edges. The value of the active controller is shown in the display in the middle of the device.
The result is shown graphical as well as numeric. The 10 last calculations can be recalled from the history.
A detailed manual can be obtained from the website.
Also available is Trivice HD for the iPad.

Great and helpful
It helped me often at my DIY projects.
Stay tuned, I heard from the developer that he will update the app for iOS11, so don't delete it if it does not work for a while. The update might take til Oct/Nov '17.
Edit: the update for iOS 11 just got live! Great job, thx much!
i like your app. feature requests:
* allow numeric input
* allow verticies to be dragged on 'display' screen
* once you have a triangle 'set up' w/b nice to make changes w/o having to start over. perhaps some way to remember the data entered and modify one of those 3 or 4 values. highlihgt entered data in gold?
yours in triangularity...
