In geometry, the biaugmented triangular prism is one of the Johnson solids (J50). As the name suggests, it can be constructed by augmenting a triangular prism by attaching square pyramids (J1) to two of its equatorial faces.
It is related to the augmented triangular prism (J49) and the triaugmented triangular prism (J51).
The 92 Johnson solids were named and described by Norman Johnson in 1966.
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)
