The TRIANGLE program solves triangle problems using
applications of the Law of Sines and/or the Law of Cosines. In
a typical problem, three known parts of a triangle are entered
and the program will calculate the other three parts. There are
19 possible cases and this program handles all of them, including
the ambiguous case of the Law of Sines. So if two triangles match
the given input, this program yields both answers. This program
also draws the triangle solutions to scale on a graphics screen
and in addition to calculating all the sides and angles it also
calculates the area and the perimeter. This program requires some
form of graphics such as CGA or EGA or VGA hardware. The program
automatically adapts to the highest graphics resolution of the
hardware it finds.
