Definition

An angle bisector is a line or ray that divides an angle into two equal parts.

Description

Angle bisectors are used in various geometric constructions and proofs, such as constructing the incenter of a triangle, which is the point where the angle bisectors of a triangle intersect. In practical applications, angle bisectors are used in design and architecture to create symmetrical and balanced structures. For students, learning about angle bisectors enhances their understanding of geometric constructions and the properties of angles, contributing to their overall mathematical proficiency.
