It is a line segment
Parallel
A line segment has two endpoints. Lines are infinite, so they have no endpoints; while rays start at one point and continue infinitely; and line segments are completely finite, so they have endpoints at both ends.

Two lines tangent to a circle at the endpoints of its diameter are parallel. See related link for proof.

There are 28 lines segments that both have their endpoints located at the vertices of a given cube.
Secants are lines that have a chord within them, and a chord is a segment that has endpoints on the circle itself.
Lines don't have endpoints, they extend indefinitely. Two line segments with a common endpoint form an angle.
In math terms:A ray is a line with one endpoint, never ending.-------->A line is like a ray, but with no endpoints.
Snap helps to connect lines to endpoints of other lines. Grid can be used for even spacings, measuring, but polar that can keep your lines perfectly horizontal or vertical
