P = Perimeter , S = Surface

# triangle solution

### 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.

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

[ Miror ] to reverse the triangle left to right.

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

[ Data ] , or key Q leave only input data. ( Note the two blanks preceding calculated values. )

[ Complementary ] give a second possible solution.

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

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

[ + ] ou [ - ] change the number of decimals to edit.

A value smaller than this precision makes the calculation impossible. Augmenting the precision may be needed.

The last calculation is memorised in a "cookie" and will be installed when this page is reloaded.

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.
