Pythagoras Theorem play online

This application uses the Pythagoras Theorem to calculate the unknown side of a right triangule.
The user has to introduce two sides of a right triangule and the app gets the other one using the Pythagoras Theorem.
We know that in a right triangule the sides that form the right angle are called legs and the third one is called hypotenuse.
The Pythagoras Theorem tells that the square of the hypotenuse is equal to the sum of the squares of the legs.
The user can introduce the legs and get the hipotenuse or introduce a leg and the hipotenuse and get the other leg.
The application shows all the operations.
