(the Triangle class) Design a class named Triangle that extends GeometricObject. The class contains the following : - Three double data fields named side1, side2, and side3 to denote three sides of the triangle. - A no-arg constructor that creates a default triangle with each side 1.0. - A constructor that creates a rectangle with the specified side1, side2, and side3 . - The constant accessor functions for all three data fields. - A constant function named getArea() that returns the area of this triangle. - A constant function named getPrimeter() that returns the perimeter of this triangle. Write a test program that prompts the user to enter three sides of the triangle, enter a color, and 1 or 0 to indicate whether the triangle is filled. The program should create a Triangle object with these sides and set the color and filled properties using the input. The program should display the area, perimeter, color, and true or false to indicate whether filled or not. (the Triangle class) Design a class named Triangle that extends GeometricObject.
