Little confusing can anyone help?

This is a bit confusing if anyone can help understand...

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(NumSides)
        {
            SideLength = sideLength;
        }
    }
}

You can't pass NumSides to the base when constructing Square, it isn't defined yet.

:point_right: Just follow the challenge instructions: "Use base to initialize NumSides to 4":

        public Square(int sideLength) : base(4)
