Dihedral:
Dihedral refers to
the intersection of two surfaces. Dihedral most immediately shares its etymology with the platonic solids: tetrahedron,
hexahedron (aka cube), octahedron, dodecahedron, and icosahedron. More distantly
dihedral shares it etymology with sit and chair. In
algebra, a dihedral group is a finite group with both rotational and reflective symmetries.
The bird ascended and began a dihedral [?] circle over the twenty acres of stumps behind Galloway's crew.
