Description

segment(Point, Point)

Given two points $A$ and $B$ , constructs the segment $stack A B with bar on top$ .

segment(Point, Vector)

Given a point $A$ and a vector $v$ , constructs the segment $stack A B with bar on top$ , where $B equals A plus v$ .

segment(Triangle, Integer)

Following the usual notation for a triangle: vertices $A subscript 1$ , $A subscript 2$ and $A subscript 3$ and sides $a subscript 1$ , $a subscript 2$ and $a subscript 3$ ; given an integer $i$ , this function returns the segment $a subscript i$ .

segment(Polygon | Polygonal, Integer)

Given a polygon or polygonal $p$ and an integer $i$ , returns the $i$ -th side of $p$ .

segment(Point)

Given a point $P$ , constructs the segment $stack O P with bar on top$ .

segment(Vector)

Given a vector $v$ , constructs the segment $stack O P with bar on top$ , where $P equals O plus v$

segment(Line)

Returns a segment that belongs to the given line.
