## Functions
template<typename Kernel >
Comparison_result | CGAL::compare_slope (const CGAL::Line_2< Kernel > &l1, const CGAL::Line_2< Kernel > &l2)
| compares the slopes of the lines `l1` and `l2`
template<typename Kernel >
Comparison_result | CGAL::compare_slope (const CGAL::Segment_2< Kernel > &s1, const CGAL::Segment_2< Kernel > &s2)
| compares the slopes of the segments `s1` and `s2`, where the slope is the variation of the `y`-coordinate from the left to the right endpoint of the segments.
template<typename Kernel >
Comparison_result | CGAL::compare_slope (const CGAL::Point_2< Kernel > &s1s, const CGAL::Point_2< Kernel > &s1t, const CGAL::Point_2< Kernel > &s2s, const CGAL::Point_2< Kernel > &s2t)
| compares the slopes of the segments `(s1s,s1t)` and `(s2s,s2t)`, where the slope is the variation of the `y`-coordinate from the left to the right endpoint of the segments.
template<typename Kernel >
Comparison_result | CGAL::compare_slope (const CGAL::Point_3< Kernel > &p, const CGAL::Point_3< Kernel > &q, const CGAL::Point_3< Kernel > &r, const CGAL::Point_3< Kernel > &s)
| compares the slopes of the segments `(p,q)` and `(r,s)`, where the slope is the variation of the `z`-coordinate from the first to the second point of the segment divided by the length of the segment.
