In a right triangle, the square of the length of one side is equal to the sum of the squares of the lengths of the other two sides. Write a program that prompts the user to enter the lengths of three sides of a triangle and then outputs a message indicating whether the triangle is a right triangle. If the triangle is a right triangle, output It is a right angled triangle If the triangle is not a right triangle, output It is not a right angled triangle
