I did what the instructions told me to do and there's an error
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 Polygon(numSides)
{
SideLength=sideLength;
}
}
}
}

9,884 PointsI think you have the signature of the Square class inside of the Polygon class.
Simon Coates
28,694 Pointsit seemed to accept:
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(4)
{
SideLength = sideLength;
}
}
}

9,884 PointsYep, that looks good! Though, calling the base constructor for Polygon should take in the sideLength.
Simon Coates
28,694 Pointsum, a single sidelength would only apply to shapes that have all equal sides. a single value would not be useful for a generic polygon.

9,884 PointsSimon Coates, you're right! I jumped the gun on that. I should have double checked. Thanks for letting me know! :)

16,598 PointsYes, at the moment your Square class is inside the Polygon class. Polygon and Square should be two separate classes, although Square inherits from Polygon. Also, don't forget to add a semicolon at the end of the SideLength field. The initialization of numSides to 4 can be done like that:
public Square(int sideLength) : base(4)

28,694 Pointsyour use of {} is probably wrong (correct indenting would make this clearer). You've added a line of code to the Polygon constructor that you don't need (and omitted the ;), and I'm not sure you need the word 'Polygon' on the line with the Square constructor. I'd assume that if you use base, it knows to use polygon.
