Description
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 !

Comments on Universal Triangle Solver for Android

★★★★☆ David Scott · Mar 2, 2016
Solves triangles with 3 pieces of info. This is a neat tool that lets you input 3 pieces of information (angles & sides) and gives you the rest of the unknowns. Of course 3 angles alone won't be useful, but it will give both possible options if you have an Angle Side situation.
★★★★☆ A Google User · Nov 15, 2014
Needs changes to font and layout for 5 stars Intuitive to use and seems accurate so far. Useful for quick checks on surveying and engineering calculations. I have only tested it in degrees setting so far. I use it mostly on a Sony tablet and wish it could be used in landscape mode. The triangle could be centered higher and the entry fields much larger. Sometimes the data entered scrolls off-screen, making it difficult to confirm an entry. It seems laid out for smaller screens. The ads at the top are not too intrusive, but they do make it hard to concentrate. Maybe instead of constantly changing, they could pop up when a new calculation is performed. I dislike that fields are prefilled by default. The area calculation is very useful. I want to try grad values, but I cannot find the menu and settings button. I have not tried any similar apps as this one serves my needs.
★★★★★ A Google User · Aug 4, 2014
I am a machinist and this app helps me all the time. Super easy to use as well.
★☆☆☆☆ A Google User · Dec 29, 2014
This must be still. Under development. Does not give accurate answers. Difficult and cumbersome user input, my rating is zero
★★☆☆☆ A Google User · Aug 10, 2014
Cut off Slightly cut off on my phone prism2

Says it needs no permissions then tries to access Internet and shell It works, but it also tries to connect to the Internet and access shell...
