Prism (geometry)
In geometry, a prism is a polyhedron with a n-sided polygonal base, a translated copy (not in the same plane as the first), and n other faces (necessarily all parallelograms) joining corresponding sides of the two bases. All cross-sections parallel to the base faces are the same. Prisms are named for their base, so a prism with a pentagonal base is called a pentagonal prism. The prisms are a subclass of the prismatoids.

Famous quotes containing the word prism:
“Neither can I do anything to please critics belonging to the good old school of “projected biography,” who examine an author’s work, which they do not understand, through the prism of his life, which they do not know.”
—Vladimir Nabokov (1899–1977)
