This .Net class (DLL) accepts 1 to 3 sides and 1 to 3 angles of a triangle in which it uses a combination of Sine and Cosine to calculate the remaining elements.
If all elements are calulated then it finds the area and perimiter as well as figures out what type of triangle it is.
I didn't create this one all on my own, I had help from a friend who goes by
{HV} Chaos.
