It it possible to create a class within a class?

It doesn't seem like I can create another tab to create a new class on.. is it even possible to create a class within a class?! that doesn't seem logical. None to less I'm super confused can someone break down whats being ask and how to attack the problem?

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

        public Polygon(int numSides) : Square(int sideLength)
        {
            NumSides = numSides;
        }
    }

}

Don't forget the warning in the instructions: "Important: In each task of this code challenge, the code you write should be added to the code from the previous task."

The original code should remain as-is and your new class can be added to the same tab. You're right that it should not go inside the other class, but both classes can be on the same tab (and inside the same namespace).
