I can't understand how: Bummer! Did you initialize the field 'numSides' to 4 in the base constructor?

Can someone help me understand. Thank you.

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 need to pass the value to the base constructor.

So instead of "base(numSides)" you would call "base(4)". The value you pass will become numSides inside the base constructor.
