The Ultimate Right Triangle solver is a powerful tool for finding any value on a right triangle. The program will prompt you to type in the side lengths and angles you already know (typing 0 for the ones you don’t know), and the program will solve for everything you are missing.
This is possible through a combination of the Pythagorean theorem and the trigonometric functions. The program also features an easy to use interface, with a diagram to help you figure out where each angle and side is located. The program is designed for the TI-84 Plus CE and TI-84 Plus C Silver Edition graphing calculators.
