## Kernel::IsDegenerate_2

A model for this must provide:

bool | fo.operator() ( Kernel::Circle_2 o)
|  | returns true iff o is degenerate.
bool | fo.operator() ( Kernel::Iso_rectangle_2 o)
|  | returns true iff o is degenerate.
bool | fo.operator() ( Kernel::Line_2 o)
|  | returns true iff o is degenerate.
bool | fo.operator() ( Kernel::Ray_2 o)
|  | returns true iff o is degenerate.
bool | fo.operator() ( Kernel::Segment_2 o)
|  | returns true iff o is degenerate.
bool | fo.operator() ( Kernel::Triangle_2 o)
|  | returns true iff o is degenerate.
