Where to Use
Use when desiring to introduce the quintessential Egyptian architectural element, the Pyramid, into a design.
Two square pyramid designs used in Egyptian architecture have medial triangles given by:
- Pi pyramid (h:b) = (4:pi) and perimeter = 2pi * height
- Golden pyramid (b:h:a) = (1 : sqrt(phi) : phi) which is a geometric progression of the sides
- 3:4:5 pyramid (b:h:a) = (3 : 4 : 5) which is an arithmetic progression of the sides
Note that the ratio of dimensions in a golden pyramid is very close to those of a pi pyramid.
Mission-style lamps often use a pyramidal shape for the light shade:
