#include <CGAL/Kernel/global_functions.h>
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/Kernel/global_functions.h>
returns an approximation of the signed dihedral angle in the tetrahedron pqrs
of edge pq
.
The sign is negative if orientation(p,q,r,s)
is CGAL::NEGATIVE
and positive otherwise. The angle is given in degrees.
p,q,r
and p,q,s
are not collinear.
