Using the Shape.java file available on moodle, extend the Shape class into the following classes: Rectangle: Define the draw() method to print a rectangle of height by width of the char stored in pattern Square: Override both setWidth and setHeight so that both values are always the same. Write the appropriate draw) method Triangle: Add a variable angle which will be set to 90 (for simplicity's sake). Override toString() to print the angle as well as the rest of the information Implement the draw() method
