In geometry, a prism is a polyhedron comprising an n-sided polygon base, a second base which is a translated copy (rigidly moved without rotation) of the first, and n other faces, necessarily all parallelograms, joining corresponding sides of the two bases.
Beyond the triangular bipyramid as its dual polyhedron, many other polyhedrons are related to the triangular prism. A Johnson solid is a convex polyhedron with regular faces, and this definition is sometimes omitted uniform polyhedrons such as Archimedean solids, Catalan solids, prisms and antiprisms. [12]
Structure of xenon oxytetrafluoride, an example of a molecule with the square pyramidal coordination geometry.. Square pyramidal geometry describes the shape of certain chemical compounds with the formula ML 5 where L is a ligand.
If faces are all regular, the pentagonal prism is a semiregular polyhedron, more generally, a uniform polyhedron, and the third in an infinite set of prisms formed by square sides and two regular polygon caps.

A Rochon Prism. A Rochon prism is a type of polariser.It is made from two prisms of a birefringent material such as calcite, which are cemented together. [1]The Rochon prism was invented by and is named after Abbé Alexis Marie Rochon.
Prisma is a satellite project led by the Swedish Space Corporation (SSC) which consist of two satellites that fly in formation. [1] Prisma is operated in collaboration with CNES , the French space agency, which provides the radiofrequency metrology system that enables the satellites to fly in close formation while autonomously avoiding collisions.
