Pythagoras Theorem Calculator

"Pythagoras" is a user-friendly implementation of the Pythagorean Theorem from geometry mathematics. It expects the length of two of the sides in a right / rectangluar triangle. The two sides that are selected can be either the two short legs or one leg and the hypotenuse. As an added bonus the application will also calculate all the angles of the triangle using sine and cosine.
There is also some general info describing the theory behind the Pythagorean Theorem to help users better understand the calculations that are being done. All formulas and calculations are shown inside the application. This can in particular be very useful for middle school students that just started learning about the Pythagoras' Theorem. Math homework will easier and so much more fun! Someone from the construction industry might also find it useful in certain situations.
Feel free to leave comments and suggestions. If there is any interest I will happily add new features, and any bugs will get my immediate attention.
The application is of course free of charge. Enjoy!
