use base to initialize NumSides

Hi, I think I figured out most of the problems. But I don't understand what it means by "initialize NumSides using base" .

Can you help me with that part? 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 side_length)
        {
            SideLength = side_length;    
        }
    }
}

You have another issue, your parameter is named "side_length", but the instructions ask for "sideLength".

And the syntax for calling the base constructor with the argument "4" would look like this:

        public Square(int sideLength) : base(4)
