PyramidsThe five triangular faces with V in common, such as ΔVAB,

such as ΔVAB, are lateral faces. These faces intersect

in segments called lateral edges.

The height of a lateral face is called the slant height, l of the pyramid.

Слайд 4 Most of the pyramids you'll study will be

Most of the pyramids you'll study will be regular pyramids. All

regular pyramids.
All lateral faces are congruent isosceles triangles.

The altitude meets the base at its center, O.

These are pyramids with the following properties:
The base is a regular polygon

All lateral edges are congruent
