The molars are in fact composed of alternating triangular prisms, with the outer folds of enamel forming deep and acute angles.

It seemed to consist of a sort of triangular prism set with its edge vertically on a rigid platform attached to a massive stand.

I must now explain to you the refraction of a ray of light, by a triangular piece of glass, called a prism.

Secondly, we are representing the ﬁeld within each ﬂuxon using sectorwise angular equipartition – essentially assuming that the currents are concentrated along the boundaries of triangular prisms around each ﬂuxon – but the Lundquist solution requires a volume current.
Fluxon Modeling of Low-Beta Plasmas
This can be solved by a “Dehn surgery”, replacing the chain of three hexagonal prisms by a chain of six triangular prisms with the same boundary — see Figure 10.
Polytopality and Cartesian products of graphs

Polytopality and Cartesian products of graphs
We need a cycle to represent it 5By a triangular cylinder we mean the surface of a 3-prism with the two end triangles missing.
