The Polygon class represents a 2 dimensional shape. It has a public field named NumSides. Create a new type of polygon c

How do I Use the base to initialize numSide to 4?

Polygon.cs 
namespace Treehouse.CodeChallenges
{
    class Polygon
    {
        public readonly int NumSides;

        public Polygon(int numSides)
        {
            NumSides = numSides;
        }
    }
        class Square : Polygon
        {
        public readonly int SideLength;

        public Square (int sideLength) : base (int Polygon),
        {
          SideLength = sideLength (4);
        }

        }
}

You have some misplaced arguments.

The challenge error message included a clue: "Bummer! Did you initialize the field 'numSides' to 4 in the base constructor?". When you call base you should pass the value 4. Also there should not be a comma after the call to base.

The argument that should have been passed to base seems to appear as a stray element on the line where SideLength is assigned. It doesn't belong here and makes it seem that you are calling sideLength as a method and passing it the argument 4.
