Inheriting constructors, in what order does the constructors execute in: The child or parents first?

How should I tell the program to set numsides to be 4 in the child class?

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;
        }
    }
}

Since NumSides is the argument for the base class, you simply pass the desired value as the argument to base:

        public Square(int sideLength) : base(4)
