Definition of Altitude (Geometry) - Math Definitions.
Altitude in Geometry. When you are in an airplane, the pilot or flight attendant probably will update you on how high up the airplane is in the air. This is known as the altitude of the airplane.Generally: another word for height. For Triangles: a line segment leaving at right angles from a side and going to the opposite corner. Here are the three altitudes of a triangle.In geometry, an altitude of a triangle is a line segment through a vertex and perpendicular to (i.e., forming a right angle with) a line containing the base (the side opposite the vertex). This line containing the opposite side is called the extended base of the altitude. The intersection of the extended base and the altitude is called the foot of the altitude.
Examples, solutions, and videos that will help GMAT students review some questions on the altitude of a triangle. The following diagrams show the altitude of an acute triangle and an obtuse triangle.

Altitude 1. An altitude of a triangle. An altitude is a line which passes through a vertex of a triangle, and meets the opposite side at right angles. A triangle has three altitudes. For more see Altitudes of a triangle. An interesting fact is that the three altitudes always pass through a common point called the orthocenter of the triangle.
