Definition of slant height in English:
The height of a cone from the vertex to the periphery (rather than the centre) of the base.
- Since in a regular pyramid the triangles are all congruent, the slant heights are the same.
- What happens to the surface area, volume, slant height, radius and height as you roll the cone tighter?
- Notice that the vertical elevation provides an infinite number of possible integer slant heights.
