Symbolic

A, B, C = length of sides

d, e, f = angles, opposite to sides A, B, C

P = Perimetre , S = Surface


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 ] to get all other values and a drawing of that triangle.

Or clik in the white left zone to directly draw a triangle. First data of A, B, C, P or S is used for calculation.

[ Rotation ] to turn the triangle on another side.

[ Reset] to erase all values.

[ Data ] 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.

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

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