Altitude of a Cone Definition
The altitude or height of a cone is the distance from the apex of a cone to its base. It is the shortest line segment between the apex of a cone and the (possibly extended) base. Altitude can also be used to refer to the specific length of this segment. The altitude of a cone is illustrated in the diagram below.
