### How to     ( Javascript must be enabled )

Input 3 values including at least one non angular one.

( d is the angle opposite to side A; e opposite to B; f opposite to C

Click button [ Calculate ] or [ Enter ] key to get all other values and a drawing of that triangle.

Or click in the white left zone to directly draw a triangle.

The 3 inputs used for solution will be highlighted in yellow background.

[ Rotation ] to turn clockwise the triangle on another side.

[ Miror ] to reverse the triangle left to right.

[ Reset] or [ Esc ] key to delete all values.

[ Data ] keeps only input data.

[ Complementary ] gives a complementary solution.

[ degree ] or [ radiant ] to change angular unit.

[ < ] or [ > ] ( at top with Triangulator # ) to go backward or forward to preceding solutions.

Scientific notation may be used. For exemble .0000123 will be presented 1.23e-5 = 1.23×10-5.

The calculation is done with the three first inputs entered according to the order A B C d e f P S.

Others values are discarded and not concorded.

An impossible calculation warning will show up with an error # specified in the Symbolic box.

Immediately after a successful calculation, you can change the number of decimal places by clicking on the [ + ] or [ - ] button.

The text in Results box can be copied and pasted to be saved elsewhere.

Pasting others results there, [ Report results ] inputs them in the calculator.
