- In geometry, a monogon, also
known as a henagon, is a
polygon with one edge and one vertex. It has Schläfli
symbol {1}. In
Euclidean geometry a monogon...
- In geometry, a
triangular prism or
trigonal prism is a
prism with 2
triangular bases. If the
edges pair with each triangle's
vertex and if they are perpendicular...
- In geometry, the 5-cell is the

symbol {3,3,3}. It is a 5-vertex four-dimensional
object bounded by five
tetrahedral cells...
- In geometry, the

digonal orthobicupola), is
formed by
gluing together two
triangular prisms on
their square faces, but
without twisting...
