1. Draw the UML diagram that involves the classes Triangle and GeometricObject. 2. Implement the class. 3. Write a test program that creates a Triangle object with sides 1, 1.5, 1, color yellow and filled true, and displays the area, perimeter, color, and whether filled or not. Problem Description: Design a class named Triangle that extends GeometricObject. The class contains: Three double data fields named side1, side2, and side3 with default values 1.0 to denote three sides of the triangle. A no-arg constructor that creates a default triangle. A constructor that creates a triangle with the specified side1, side2, and side3. The accessor methods for all three data fields. A method named getArea(). that returns the area of this triangle. A method named getPerimeter(). that returns the perimeter of this triangle. A method named toString.(). that returns a string description for the triangle. For the formula to compute the area of a triangle, The tostring_()_ method is implemented as follows: return "Triangle: side = " + side 1+ " side 2="+ side + +
