A cube has six pairs of intersecting line segments. These six pairs will total 72 lines in a cube.
Twelve line segments are in a cube

Four pairs, which intersect at the four vertices!
There are 28 lines segments that both have their endpoints located at the vertices of a given cube.

A circle is a continuous curve. A vertex is the intersection of two (or possibly more) line segments. A circle has no intersecting line segments. It is a curve, and does not have a vertex or vertices. None at all.
there are infinitely many segments in a line.
