Question

midpoint of a segment
the midpoint of a segment is a point that divides the segment into 2 equal parts.
a line, ray, or segment that intersects a segment at its midpoint is said to bisect the segment and is called the bisector.
in the diagram to the left, _ is the midpoint of _ and _ is a line _

Explanation:

The mid - point of a segment is a point that divides the segment into 2 equal parts. A line, ray, or segment that intersects a segment at its mid - point is called the bisector of the segment. In the given diagram, point B is the mid - point of the segment with endpoints not fully specified but assumed to be some points on the line containing B.

Answer:

The mid - point of a segment is a point that divides the segment into 2 equal parts. A line, ray, or segment that intersects a segment at its mid - point is called the bisector of the segment. In the diagram to the left, B is the mid - point of a segment (endpoints not fully shown).
