1. Download the Main, Shape, Rectangle and Circle class under the latest module. Create the Triangle class below. Rectangle, Circle, and Triangle are all subclasses of Shape. a. Your default constructor should set the color to pink and striped to false. Each side should be set to 0 . b. For the isValid method, a triangle is valid if the sum of its two sides is greater than the third side. - A side should not be set if the Triangle would not be valid with the change. - A new Triangle object should not be created if the Triangle is not valid. c. The equation for finding the perimeter of a Triangle is: perimeter=side1+side2+side3 d. For the equals method, two Triangles are equal if all sides are equal and if all of the conditions in the Shape class's equals method are met. (HINT: use super) e. The toString should print out the perimeter and color of the Triangle object. f. Run your program. I added a test program in the main header. g. There is a Triangle object, called t1 : Triangle t1= new Triangle0; Which method calls will work and which will not? Try running each. - t1.toString0; - t1.getWidth(; - t1.getSide10; - t1.getNumOfSides(
