What is a bisector?

About what a bisector is, you can learn from the school course of geometry.

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

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