segment bisector
a line, segment, or ray that cuts a segment into two equal parts
A segment bisector is a line, ray, or line segment that divides a given line segment into two equal parts or halves. In other words, if we draw a line segment from one endpoint of the given segment to the midpoint of that segment, it will divide the original segment into two congruent or equal parts. Thus, the segment bisector is the line that passes through the midpoint of the segment. A segment bisector has several important properties:
1. It divides a line segment into two congruent segments.
2. It passes through the midpoint of the segment.
3. It is perpendicular to the given segment at its midpoint.
4. It divides any angle into two congruent angles.
Segment bisectors are essential tools in geometry and used in many constructions, calculations and proofs. For instance, a perpendicular bisector of a line segment can be used to construct a perpendicular line to that segment at its midpoint. Similarly, an angle bisector is a line that divides an angle into two equal parts, and it is used to solve problems involving triangles and circles.
