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.
