### Definition

#include <CGAL/Polygon_2_algorithms.h>

template <class ForwardIterator, class Traits>

bottom_vertex_2 ( | ForwardIterator first, ForwardIterator last, Traits traits)

|  | Returns an iterator to the bottommost point from the range [first,last). In case of a tie, the point with the smallest x-coordinate is taken.

### Requirements

1. Traits is a model of the concept PolygonTraits_2 . In fact, only the members Less_yx_2 and less_yx_2_object are used.
2. ForwardIterator::value_type should be Traits::Point_2,
