If you know three attributes of a triangle (at least one of them being a side) you can find the rest using trigonometry. This application does just that for you! The angles are named by big letters, and the sides by small letters in accordance with the example triangle. Press example if you aren't completely sure what to do. Only the first triangle is shown in the drawing when more than one solution is possible.

Enter exactly three attributes about the triangle to find the other attributes.
