The Polygon class represents a 2 dimensional shape. It has a public field named NumSides. Create a new type of polygon called Square. It should have a public readonly field named SideLength that’s initialized using the constructor. Use base to initialize NumSides to 4.

this is what I have. It's telling me I need to initialize the field numSides to 4 in the base constructor

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 Polygon(4)
        {
            SideLength = sideLength;

        }
    }

}

Disregard, I figured it out. Just to answer it in case others look, I specified public Square(int sideLength) : base Polygon(4)

The correct syntax would be public Square(int sideLength) : base(4)
