A proportionally correct triangle is drawn after the calculations.
The triangle can be rotated and mirrored.
The number of decimals for lengths, angles and area can be specified.
Possibility to reuse and edit the last specified values after clearing.
Possibility to change the color theme on backgrounds.

Ratings and reviews

Brilliant! Love that the triangle changes shape and you can rotate it, perfect for visualising what you are applying the trig to. Only gripe is that you cannot just change values after entering them, you have to re enter all the values, which is a pain when you are using the app in certain circumstances.

Simple and perfect, colour scheme a nice touch too. Thanks.

I can hardly believe how often I use this app! Super simple to use with a clear user interface.
