That would be classified as an edge.
Two planes that intersect do that at a line. neither a segment that has two endpoints or a ray that has one endpoint.

Edge. (:
A straight line segment can be drawn by joining any two points.A straight line segment can be extended indefinitely in a straight line.Given a straight line segment, a circle can be drawn using the segment as radius and one endpoint as center.All right angles are congruent.If two lines are drawn which intersect a third in such a way that the sum of the inner angles on one side is less than two right angles, then the two lines inevitably must intersect each other on that side if extended far enough.

All bisectors intersect the line segment at the midpoint. There can be multiple bisectors, intersecting at the midpoint at different angles, but they all intersect the line segment at its midpoint. The midpoint separates the line segment into two equal halves.

It is a bisector.
A line segment can be defined as having two endpoints
Not quite. Those line segments are the lines which are the edges of the faces.
