|Fig 987.137C Net diagram of Angles and Edges for Basic
Equilibrium 48 LCD Triangle in Vector
Equilibrium Grid: This is a coded detail of the basic
spherical triangle shown shaded in Fig.
and at Fig.
It is the key to the trigonometry
tables for the spherical central angles, the spherical
face angles, the planar edge lengths, and the planar
face angles presented at Table
drawing shows the spherical phase: angle and edge ratios
are given for both spherical and planar phases.)
