Segment

segment(Point, Point)

segment(Point, Vector)

segment(Triangle, Integer)

 Polygonal, Integer)

segment(Point)

segment(Vector)

segment(Line)

Given two points $A$ and $B$, constructs the segment $\overline{AB}$.

Given a point $A$ and a vector $v$, constructs the segment $\overline{AB}$, where $B=A+v$.

Following the usual notation for a triangle: vertices $A_1$, $A_2$ and $A_3$ and sides $a_1$, $a_2$ and $a_3$; given an integer $i$, this function returns the segment $a_i$.

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

Given a point $P$, constructs the segment $\overline{OP}$.

Given a vector $v$, constructs the segment $\overline{OP}$, where $P=O+v$

Returns a segment that belongs to the given line.
