This base class for some shapes I have in my game looks like this. Some of the shapes can be resized, some of them can not.

   private Shape shape;

    public virtual void SetSizeOfShape(int x, int y)
    {
        if (CanResize()){
            shape.Width = x;
            shape.Height = y;
        }
        else {
            throw new Exception("You cannot resize this shape");
        }

    }
    public virtual bool CanResize()
    {
        return true;
    }

In a sub class of a shape that I don't ever want to resize I am overriding the CanResize() method so a piece of client code can check before calling the SetSizeOfShape() method.

    public override bool CanResize()
    {
        return false;
    }

Here's how it might look in my client code:

    public void DoSomething(Shape s)
    {
        if(s.CanResize()){
            s.SetSizeOfShape(50, 70);
        }
    }

Is this violating LSP?
