// General : The program will get three angles and prints weather those angles are legal for a triangle or not. If they do, it will also print the kind of the triangle.
//
// Input   : Three numbers that should represent triangle angles.
//
// Process : The program checks weather the sum of the angles is 180 and that they are above zero.
//
// Output  : Prints if those are legal angles for a triangle, and the kind of the triangle.
