Two is enough to connect each point to at least one other. Three is enough for an open net.
Six to connect every point to each of the rest.
The question should be more specific.
A line segment would connect two points on a plane.
The shortest distance between two points is a line, or a line segment. If you have two points, and you know they are part of a line, you can connect them with a line.
If you take two points and you connect them, that is a line segment. A line stretches infinitely in two directions.
45 points
A line segment has end points
Any line segment has infinitely many points and each one of them is specific to that line segment.
A line segment has two end points. This is called an line segment.
A line segment is a line with two points. When drawn, there are no arrows coming out of the points.
The definition of a segment is a line between two points.
Use two line segments (line A and line B) with all points on line A equidistant from all points on line B; in otherwords, use 2 parallel lines. Choose two points on line A (points a and b). Now choose 2 points on line B (x and y) so that the distance of line ab equals the distance of line xy. Connect points a and y with a line segment ab and points b and z with a line segment bz. In simpler words, take two parallel line segments of equal length, and connect their endpoints with two other line segments.
It will have end points to be a distinct line segment
'Line Segment' is a portion of a line that includes two points and all of the collinear points between the hypothetical two points also 'Line Segment' because a line or line segment is a set of infinite points and the infinite points are collinear....
