Question IV: Design a class named Triangle that extends the GeometricObject class given in the textbook. The Triangle class contains: Three float data fields named side1, side2, and side to denote the three sides of the triangle A constructor that creates a triangle with the specified side1, side2, and side with default values 1.0. The accessor (getter) and mutator (setter) methods for all three data fields. The class should throw a RuntimeError exception if the three given sides cannot form a triangle (if one of sides is o or less than 0.) A method named getArea() that returns the area of this triangie A method named getPerimeter() that returns the perimeter of this triangle. A method named _e_Iselt, other) that checks whether two triangles are equal of not by comparing their three sides. For example, if a triangle has side lengths 4,1,3 and another one has side lengths 3,4,1 then they should be accepted equal. A method named _str_0 that returns a string description for the triangle. The_str_0 method is implemented as follows: return "Triangle: side 1. stride) side2= strfside)." side3 = strtside}} Implement the Triangle class. Write a test program that generates triangles with three sides of the triangle, a color, and 1 or 0 to indicate whether the triangle is filled. The program should generate three Triangle objects. Two of these triangles should have the same side lengths. The program should display triangle's area, perimeter, color, and True or False to indicate whether the triangle is filled or not. The program should also compare triangles with each other whether they are equal or not
