This works for any location of the apex, provided that h is measured as the perpendicular distance from the plane which contains the base.
The height is the perpendicular distance between the base and the opposite face.
The fork offset is the perpendicular distance from the steering axis to the center of the front wheel.
This perpendicular distance is called the moment arm.
The vertical height (or altitude) which is the perpendicular distance from the top down to the base.
The height of a frustum is the perpendicular distance between the planes of the two bases.
Depending on how they are generated, depth maps may represent the perpendicular distance between an object and the plane of the scene camera.
A moment is force times the perpendicular distance from the fulcrum to the line of action of the force.
In geometry, "altitude" refers to the perpendicular distance from the base of a figure to its highest point.
The height (or altitude) is the perpendicular distance between the bases.
