True. What's the question?
The height or altitude of a pyramid is the perpendicular distance from the plane of the base to the apex.
The slant height of one face of a pyramid is the perpendicular distance from the base edge of that face to the apex.
If one face of the pyramid is perpendicular to the base, the slant height of that face would be the same as the altitude--for that pyramid. (This configuration is not normally what we think of when we think of a pyramid, but the definitions do not rule it out.)
