Understanding Bisectors in Geometry | Exploring Line Segment and Angle Bisectors

Definition of a Bisector

A bisector is a line, segment, or plane that divides a given object into two equal parts

A bisector is a line, segment, or plane that divides a given object into two equal parts. In mathematics, we commonly refer to the bisector of a line segment or an angle.

1. Bisector of a Line Segment:
The bisector of a line segment is a line or a segment that divides the line segment into two equal parts. It passes through the midpoint of the line segment. The bisector of a line segment is perpendicular to the line segment and it divides the line segment into two congruent parts.

For example, in the line segment AB, the bisector is a line or segment that passes through the midpoint of AB, forming two congruent line segments AC and CB.

2. Bisector of an Angle:
The bisector of an angle is a straight line or ray that divides the angle into two equal parts. It basically cuts the angle into two congruent smaller angles.

For example, in the angle XYZ, the bisector is a line or ray that divides the angle into two smaller angles, angle XYZ and angle YZB, which are congruent.

Bisectors are important in geometry as they help us determine the midpoint of a line segment or the measure of an angle, and aid in solving various geometric problems.
