an edge.
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.
No. Consider two adjacent faces on a cuboid. Both planes are parallel to the edge at which the intersect. But the fact that they do intersect illustrates that they are not parallel.
How am i supposed to kow this??? I am in second grade!
Take a compass, extend it about 3/4 of the length of the segment. Then from one end of the segment, draw a 180 degree arc. From the other end draw another arc. Connect the points where the arcs intersect. Where the line intersects with the segment is the midpoint of the segment. That is how you bisect a segment to find the midpoint - geometrically.
It is an edge.

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.
90 degrees
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.
