Classify Triangules

This application tells the user the type of the triangule knowing its sides: right, acute or obtuse triangule.
We use the Generalized Pythagoras Theorem. We square the three sides of the triangule:
If the biggest side squared is equal to the sum of the smallest sides squared, we have a right triangule.
If the biggest side squared is greater than the sum of the smallest sides squared, we have an obtuse triangule.
If the biggest side squared is smaller than the sum of the smallest sides squared, we have an acute triangule.
