# What is a bisector?

The fact that such a bisector can be found in the school geometry course.

The angle bisector (derived from the Latin bi - double, sectio - separation, cutting) is a ray having a beginning at the apex of a corner that divides this angle into two equal angles. The locus of points that are equidistant from the sides of the corner is a bisector.

The bisector of the angle of a triangle is the bisector of this angle, ending at the point of intersection with the opposite angle by the side of the triangle, forming a segment from the point of intersection to the vertex of the angle.
