Final answer:
A line segment or ray intersecting a line segment at its midpoint is indeed a segment bisector, making the statement true. It divides the line segment into two equal parts.
Step-by-step explanation:
The statement that a line segment, or ray that intersects a line segment at its midpoint is a segment bisector is True. A segment bisector is a line, ray, or another segment that divides a line segment into two equal parts at the midpoint. By definition, intersecting a segment at its midpoint means cutting it into two congruent segments, hence bisecting it. This is a fundamental concept in geometry and is used, for example, to determine symmetry or calculate midpoints in geometric figures.
