What is something that bisects?

Something that bisects is referred to as a bisector. A bisector divides an object into two equal parts, usually at a straight angle, ensuring that the two portions are mirror images of each other in terms of size and shape. In geometry, there are commonly two types of bisectors:

1. Perpendicular bisector: A line or a line segment which cuts another line segment into two equal parts at a 90-degree angle. For example, the perpendicular bisector of a line segment will pass through the midpoint of the segment and will be perpendicular to it.

2. Angle bisector: A line or a line segment that divides an angle into two congruent angles, each having half the measurement of the original angle. It starts at the vertex of the angle and passes through the interior, cutting it into two equal angles.

In the broader sense, the term “bisect” can be applied in various other contexts where something is being divided into two equal parts.
