Extracted text: Implement a class Quadrilateral that represents a quadrilateral shape, based on the coordinates of its four corners. The getShapeType method returns a string that describes the quadrilateral's shape. Use this template: Quadrilateral.java Examples: Quadrilateral q1 new Quadrilateral (5, 10, 15, 10, 15, 20, 5, 20); q1.getShapeType (); // returns "Square" Quadrilateral q2 = new Quadrilateral(5, 0, 25, 0, 30, 198, 0, 30); q2.getShapeType (); // returns "None" Quadrilateral q3 = new Quadrilateral (9, -0.33, -29.25, -0.33, -29.25, 16.77, 9, 16.77); q3.getShapeType (); // returns "Rectangle" Quadrilateral q4 = new Quadrilateral (5, 0, 25, 0, 30, 30, 0, 30); q4.getShapeType (); // returns "Trapezoid" Quadrilateral q5 new Quadrilateral(7.4315, 0, 14.863, 8.11, 7.4315, 16.22, = 0, 8.11); q5.getShapeType (); // returns "Rhombus" Quadrilateral q6 = new Quadrilateral (0, 0, 4, 0, 3, -2, -1, -2); q6.getShapeType (); // returns "Parallelogram"
