Function Documentation

template<typename Kernel >
Angle CGAL::angle ( const CGAL::Point_2< Kernel > &  p,
const CGAL::Point_2< Kernel > &  q,
const CGAL::Point_2< Kernel > &  r 
)

returns CGAL::OBTUSE, CGAL::RIGHT or CGAL::ACUTE depending on the angle formed by the three points p, q, r (q being the vertex of the angle).

The returned value is the same as angle(p - q, r - q).

#include <CGAL/global_functions.h>

template<typename Kernel >
Angle CGAL::angle ( const CGAL::Point_2< Kernel > &  p,
const CGAL::Point_2< Kernel > &  q,
const CGAL::Point_2< Kernel > &  r,
const CGAL::Point_2< Kernel > &  s 
)

returns CGAL::OBTUSE, CGAL::RIGHT or CGAL::ACUTE depending on the angle formed by the two vectors pq, rs.

The returned value is the same as angle(q - p, s - r).
