Equilateral-Triangle-Enclosure — Enclosure

Geometry Class
Enclosure
Geometry Id
Equilateral Triangle Enclosure
Configuration Notes
3-Surface enclosure: F11+F12+F13=1; F11=0 (flat); by Symmetry F12=F13=0.5. Equivalently: 3-Surface Rule for Three Equal Flat surfaces. F21=F12=0.5 When Areas Are equal.
Formula Expression
F12=0.5 by symmetry; F II=0 for All Flat Surfaces
