In my Trig class, we are going over Laws of Sin and Heron's Formula. I am making a program where a user can enters the angles and the side of a oblique triangle and whatever is left blank the program will calculate the rest sides and angles that the user did not enter.

My program can also calculate the area if all the sides of the triangle are given.

Knowing the math and formulas is not a problem for me, The problem is just figuring out which sides and/or angles to calculate. Instead of having a thousand if statements!

Here is my source for far. I attached a .zip file containing my source.

Help will be greatly appreciated!

i agree. law of cosines can solve some problems that take more steps with the other two formulas

use 500 if statements instead, i think 1000 is a few too many

The law of sine and cosine aren`t constrained by the names of the angles or sides. The user just has to input the values and according to them the program has to evaluate the answer. Just put the picture triangle and tell the user to input the values accordingly.
