+Write a command line program that:
 
+Has classes to allow number of shapes to be defined: square (side1), rectangle(side1, side2), circle(radius), triangle(height, base).
 
+Each shape class should know it’s type (“Square”), how many sides it has.
+
+Each shape needs to be able to calculate it’s perimeter and area. For the triangle you can assume it is isoceles and the perimeter can be computed using
+, where
+ is the base and
+ is the height.
+
+Within the Main method create a variety of the shapes and put them in a list
+
+Create a class ShapeSorter which should contain four methods
+
+Print out the Shapes that match a chosen type
+
+Print out the Shapes that match a chosen number of sides
+
+Print out the Shapes in order of area descending
+
+Print out the Shapes in order of perimeter descending
