Definition
Let a perpendicular $AE$ be dropped from the apex of a cone to the plane containing its base.
The line segment $AE$ is an altitude of the cone.

The word altitude is often used in the context of a geometric figure to mean the height.
However, on $\mathsf{Pr} \infty \mathsf{fWiki}$ it is preferred if the terms altitude and height are used specifically to mean respectively the perpendicular and its length, to avoid confusion.
