Définition(s)

  • In geometry, a parallelepiped is a three-dimensional figure formed by six parallelograms (the term rhomboid is also sometimes used with this meaning). By analogy, it relates to a parallelogram just as a cube relates to a square. In Euclidean geometry, the four concepts—parallelepiped and cube in three dimensions, parallelogram and square in two dimensions—are defined, but in the context of a more general affine geometry, in which angles are not differentiated, only parallelograms and parallelepipeds exist. Three equivalent definitions of parallelepiped are
    - a polyhedron with six faces (hexahedron), each of which is a parallelogram,
    - a hexahedron with three pairs of parallel faces, and
    - a prism of which the base is a parallelogram.
