 The angle opposite the base is known as the vertical angle, and the vertex of this angle is called the vertex of the triangle. The altitude of a triangle is the perpendicular distance from the vertex to the base or the base produced.

...When any side has been taken as base, the opposite angle is called the vertical angle, and its vertex is called the vertex of the triangle. The altitude of a triangle is the perpendicular drawn from the vertex to the base. 68. Since a straight line is the shortest distance between two points,... | |
