1. Regular Square Pyramid h l Vertex Lateral Edge Height Slant Height
Centroid
The base of a pyramid can be
any polygon (not only squares).
The vertex (highest point) of a right pyramid lies
directly above the centroid (basically the center) of the base.
Regular pyramids are special cases
of right pyramids.
Regular pyramids are right pyramids
with regular polygon bases.
All the lateral edges and faces of regular pyramids
are congruent.

2. Using a “net” to create area formulas

3. A regular square pyramid has base edge of 6m and lateral edge of 5m.
Slant height =
Lateral Area =
Base Area =
Total Area =
Length of altitude =
Volume =

4. Lateral Area = Base Area = Total Area =
Given: Regular Triangular Pyramid, Slant height = 9cm Base perimeter = 12cm
Lateral Area =
Base Area =
Total Area =
