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.

An octagon has 8 faces and 8 edges. Each face of an octagon is a straight line segment, and each edge is a line segment where two faces meet. The total number of faces and edges in an octagon can be calculated by adding the number of faces and edges together, which equals 16.

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.
Two planes that intersect do that at a line. neither a segment that has two endpoints or a ray that has one endpoint.

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.
