In mathematics, the height line (or height and vertical line) of a triangle is a straight line perpendicular to the opposite side through one of its vertices, or a line segment from the vertex to the intersection with the opposite side. The intersection of the high line and the opposite side is called vertical foot. The length of the high line passing through a vertex is called the height of the triangle around the vertex (or the opposite side).

In fact, a vertex of a triangle becomes perpendicular to this point, which is a straight line.

A high line will not bisect a triangle.

If you really want to bisect, two lines that can connect two bisectors of a vertex and an opposite side will bisect the triangle area.
