create a class diagram for a shape class. shapes have a name, an x coordinate and a Y coordinate. the two coordinates give the position of the shape. make sure that you show the visibility of all fields and methods. Extend the above class diagram for shape by adding three derived classes; circle, triangle and rectangle. the classes will have the following additional fields: circle: radius triangle: base, height rectangle: width, height

Note: don't wirite in a programming language it is a class diagram
