Examples
-
Thus, the median dihedral angle varies smoothly during textural equilibration, from its original (and highly variable) value created during grain impingement, toward the commonly lower (and less variable) values typical of solid-melt equilibrium.
Academic text (2018) -
The equilibrium dihedral angle for the cases under consideration here is reported in Table 4.

In fact, the dihedral angle decreases from 81 to 61 (9) degrees, a tendency also confirmed by the NMR value of 53 degrees measured for the analog complex in water.
Academic text (2001) -
In geometry class, we learned that the dihedral is the angle at which two flat surfaces meet.
-

Morphology
dihedral = di + hedr + al
Although 'di-' suggests 'two', the classical stem 'hedr' and the technical geometric meaning are not transparent to an average B1 learner.
Etymology
Dihedral comes from the Greek parts di- 'two' and -hedral 'face'. So a dihedral is simply the angle where two planes or 'faces' meet, which is why chemists and engineers use the word to describe how parts sit in space.
