Line Segment

A line segment (sometimes also referred to as a line, though technically "line" refers to a 1-dimensional space of infinite extent) is 2 connected points. It can also be thought of as the set of all points the same distance from another in one-dimensional space; thinking about it this way, it is the 1D hypersphere.

Hypervolumes

 * vertex count =$$2$$
 * edge length =$$l$$

Subfacets

 * 2 points (0D)
