Extending the Chapter 10 shapes example

Perform the following:

• Create an Interface called IDisplayShapeInfo that specifies the following methods:
  • DisplayShapeStatistics with return type String
  • DisplayArea with return type String
• Create an Interface called ICalculateVertices that specifies the following methods:
  • TotalVertices with return type int
  • TotalSides with a return type of int
• Have the GeometricFigure class implement the IDisplayShapeInfo interface:
  • DisplayShapeStatistics will display current object type (use GetType) and the current object area (use the Area function that you wrote).
  • DisplayArea like above but only display the area.
• Finish the Rectangle, Square and Triangle classes:
  • Add properties Height and Width with proper {get; set;}.
  • Finish the constructors for these classes to allow us to set height and width at instantiation time.
  • Uncomment the code in the ComputeArea functions for each class.
• Have the Rectangle and Triangle classes implement the ICalculateVertices interface:
  • TotalVertices will return 3 for Triangle and 4 for Rectangle;
  • TotalSides will also return 3 for Triangle and 4 for Rectangle;
• Have the Rectangle and Triangle classes override with their own version of the IDisplayShapeInfo method:
  • DisplayShapeStatistics will display current object type, area, height, width, vertices and sides.
• Have the Square class override with its own version of the IDisplayShapeInfo method:
  • DisplayShapeStatistics will display current object type, area side length, vertices and sides.
• Create a new class called Circle that inherits from GeometricFigure with the following:
  • A Radius float property with proper {get; set;}
  • A constructor method that allows Radius as an argument.
  • A ComputeArea method that uses Math.PI to compute the area based on Radius.
  • Override DisplayShapeStatistics to display object type, area and radius.
• In the Program.Main method:
  • Instantiate a Triangle, Square, Rectangle and Circle.
  • Use Console.Writeline to show DisplayShapeStatistics for each.
