Write a program that asks the user to supply three points (x & y coordinates).  It will then assume that these three points are a triangle, and provide you with the length of each side and the angles between them.  You will need to use the Scanner object, the Point object, and the Math class.  There should be a method that accepts the three points as parameters, do the computations, and prints the results in the output window. 

Use a WHILE loop to ensure that only valid numbers are entered; for example: 

while (!in.hasNextInt()) 

{ 

     in.next(); 

     System.out.println(“Not an integer; try again.”); 

     System.out.println(prompt); 

}
