ULTIMATE   TRIANGLE   CALCULATOR

The above graphic depicts 4 instances of solving forANY type of triangle.   However, unlike right triangles, you now need THREE pieces of information instead of two.

Diagram 1 needs no explanation.

For case 2   (abbreviated S-A-S), you must use an included angle (the angle between the two sides).

For case 3   (abbreviated A-S-A), you must use an included side (the side between the two angles).

For case 4, only the ratio of the 3 sides can be determined. If you input the smallest angle in the "ANGLE 1" box, then the shortest side will have a value of 1. If you input the largest angle in the "ANGLE 1" box, then the longest side will have a value of 1.
