The short and easy: Essentially, you tell the program any 3-unit combination of sides and angles (except three angles) and it will tell you all the sides, all the angles, the area, height, perimeter, and triangle type. It will also show you a to-scale drawing of the triangle.

New in this Version

• Mainly documentation changes
• Elimination of some obscure bugs

• Displays all angles, all sides, area, height, perimeter, and triangle type (two screens)
• Displays a to-scale drawing of the triangle (no window sizing required)
• Save option for triangle specs and/or triangle pic
• Small size and great ease of use, as compared to other programs of the same nature
• Support for both solutions of ASS triangles
• Deletes all the variables it uses
• Support for impossible (complex) triangles

This program is very easy to use and is generally self explanatory. If know much about this sort of thing, you can probably just execute the program. Otherwise, read the rest of this section.

The first time (and only the first time) this program is executed, it takes a minute to work (after that, it will execute immediately). When executed, it will show the title, my name, and my e-mail address. You then pick one of the information triplets on the menu using the F keys. To quit, press "More" then "F1."

The program will then request the data. Enter the data, pressing Enter after each entry. You will then be shown the angles, sides, and area of the triangle. Press "F1" for the second screen of data. Press "F2" to enter a new triangle. Press "F3" to see a pic of the triangle. Press "F4" to save the triangle specs to the list TriL in the format {A,B,C,a,b,c,height,area}. Press "F5" to leave the program.

On the second data screen, press "F1" to go back to the first screen. The rest is the same. On the pic screen, "F1" goes back to the first data screen and "F3" saves the pic as "Tria".

When quitting the program, you will momentarily see a the axis lines. Ignore them. The program is simply changing the graph settings to default.

Notes

• Side Effects: The program will unselect all of your graph equations, set the graph settings to default, and set the decimal mode to float. This may seem annoying, but it was necessary for the drawing system.
• The equations used in the program were the law of sines (a/sin A= b/sin B= c/sin C) and the law of cosines (c^2= a^2 + b^2 -2ab cos C)

This program has been thoroughly tested for accuracy. However, I am not responsible for any missed math problems solved by this program.
