Whats going on?

I don't understand how i use base to initialize NumSide to 4?

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

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

        public Square(int sideLength)
        {
            SideLength = sideLength;
        }
    }
}

If Polygon is your base class, then you want to make sure you have a proper constructor for the class before you can utilize base in another class.

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

        // working constructor that sets numSides and sideLength
        public Polygon(int numSides, int sideLength)
        {
            NumSides = numSides;
            SideLength = sideLength;
        }
    }
}

Now if you want to be able to create a new class that inherits from Polygon, say Square:

namespace Treehouse.CodeChallenges
{
    class Square : Polygon
    {
        // working constructor that sets numSides and sideLength
        public Square(int sideLength) : base(4, sideLength)
        {

        }
    }
}

Great Answer :D
