ANTIPRISMS
Two
congruent regular polygons (the bases),
in parallel planes. One
base is twisted so that each of its
vertices is midway between two
vertices of the other, to each of
which it is joined. The
side faces are triangles While
twisting one of the prism's bases,
the square side faces of the prism
are folded into triangles, and the
result is an antiprism The
code of an antiprism is { |
