Write a program that accepts the lengths of three sides of a triangle as inputs. The program output should indicate whether or not the triangle is a right triangle.

Recall from the Pythagorean theorem that in a right triangle, the square of one side equals the sum of the squares of the other two sides.

Use The triangle is a right triangle. and The triangle is not a right triangle. as your final outputs.

An example of the program input and proper output format is shown below:

Enter the first side: 3 Enter the second side: 4 Enter the third side: 5 The triangle is a right triangle.
