Not sure how to initialize NumSides to 4 using the base. The hint provided does not help at all.

Simply need the correct answer to this challenge, and I should be able to figure out the syntax...

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 Polygon (int numSides)
        {
            numSides = 4;
            SideLength = sideLength;
        }
    }
}

You're over-thinking this one.

What the hint was trying to say is to literally pass the number 4 as the argument to base:

        public Square(int sideLength) : base(4)

Also, there's no numSides (with lower-case "n") property (nor is one needed).

Thank you, Steven. It totally makes sense to me now.
