template<typename Kernel >
bool CGAL::parallel (const CGAL::Line_2< Kernel > &l1, const CGAL::Line_2< Kernel > &l2)
 returns true, if l1 and l2 are parallel or if one of those (or both) is degenerate.
 
template<typename Kernel >
bool CGAL::parallel (const CGAL::Ray_2< Kernel > &r1, const CGAL::Ray_2< Kernel > &r2)
 returns true, if r1 and r2 are parallel or if one of those (or both) is degenerate.
 
template<typename Kernel >
bool CGAL::parallel (const CGAL::Segment_2< Kernel > &s1, const CGAL::Segment_2< Kernel > &s2)
