  b) Create the abstract class Quadrilateral, which is a Polygon * This class will simply have a constructor to initialize Polygon's array c) Create the class Square which is a Quadrilateral. * The area method will compute base * height, where, given any three consecutive points in the array, the first two points could be considered the base, and the last two could be considered the height d) Create the class kite, which is a Quadrilateral. * This class has two private doubles representing the lengths of the diagonals of the Kite, though the constructor will not require parameters for these privates * The constructor will call a method calculate Diagonals(), which willinitialize the privates by assigning the distance between the Point2D objects at indices and 2 of the array to the first private, and the distance between the Point2D objects at indices 1 and 3 to the second private Method area will calculate and return one-half the product of the diagonals
