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. <!p><! //20> <! //20 [ + ] or [ - ] changes the number of decimals to edit; default = 4.>
<! //20> <! A value to small for this number of decimals will be presented in scientific notation.> Scientific notation may be used. <!p><! //20> For exemble .0000123 will be presented 1.23e-5 = 1.23×10-5. <!p> <!//20 Augmenting the precision may be needed when the calculation is impossible.>
The last calculation is recorded 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.
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.
Here is a practical multi calculator of angles : Calcangle
and ( in french ) a super calculator : RECALCU.
