The altitude (height) of a triangle is a perpendicular line segment from a vertex to the opposite side (or its extension), and all three altitudes of any triangle intersect at a single point called the orthocenter, which may lie inside or outside the triangle depending on whether the triangle is acute, right, or obtuse.
