C# Objects Polygon class challenge

I am not sure where i am going wrong? I cant find a way to create a second file for the Square class so i just created it within the namespace. I am getting a message asking if i defined my Square class? I have it set as the child of polygon? Any help would be appreciated.

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

        public Polygon(int numSides)
        {
            NumSides = numSides;
            numSides = 4;
        }

    }
    class Square : Polygon

    public readonly int SideLength;

    public Square(int sideLength) : base(int numSides)
    {
        SideLength = sideLength;
    }
}

i figured it out, first i removed the numSides = 4 initiation and declared the base as per directions to be 4. next i read through each line and discovered that i was missing a { after the square class, resulting in a missing one at the end.

You're pretty close.

But you omitted the braces that enclose the body of your Square class. Take a look at the Polygon class as an example.

Also, when they instructions say, "Use base to initialize NumSides to 4", they literally mean pass the number 4: "base(4)" (The base constructor is the one in Polygon).

And don't modify the Polygon class itself. But luckily, the line you added doesn't really do anything.
