  2. Solid geometry - Wikipedia

    en.wikipedia.org/wiki/Solid_geometry

    A solid figure is the region of 3D space bounded by a two-dimensional closed surface; for example, a solid ball consists of a sphere and its interior. Solid geometry deals with the measurements of volumes of various solids, including pyramids, prisms (and other polyhedrons), cubes, cylinders, cones (and truncated cones). [2]

  3. Point groups in three dimensions - Wikipedia

    en.wikipedia.org/wiki/Point_groups_in_three...

    Up to conjugacy, the set of finite 3D point groups consists of: § The seven infinite series of axial groups, which have at most one more-than-2-fold rotation axis; they are the finite symmetry groups on an infinite cylinder, or equivalently, those on a finite cylinder. They are sometimes called the axial or prismatic point groups.

  4. Pyramid (geometry) - Wikipedia

    en.wikipedia.org/wiki/Pyramid_(geometry)

    A right pyramid is a pyramid whose base is circumscribed about a circle and the altitude of the pyramid meets the base at the circle's center; otherwise, it is oblique. [12] This pyramid may be classified based on the regularity of its bases. A pyramid with a regular polygon as the base is called a regular pyramid. [13]

  5. Tetrahedron - Wikipedia

    en.wikipedia.org/wiki/Tetrahedron

    In geometry, a tetrahedron (pl.: tetrahedra or tetrahedrons), also known as a triangular pyramid, is a polyhedron composed of four triangular faces, six straight edges, and four vertices. The tetrahedron is the simplest of all the ordinary convex polyhedra .

  6. Elongated pyramid - Wikipedia

    en.wikipedia.org/wiki/Elongated_pyramid

    In geometry, the elongated pyramids are an infinite set of polyhedra, constructed by adjoining an n-gonal pyramid to an n-gonal prism. Along with the set of pyramids, these figures are topologically self-dual. There are three elongated pyramids that are Johnson solids: Elongated triangular pyramid (J 7), Elongated square pyramid (J 8), and

    The elements of a polytope can be considered according to either their own dimensionality or how many dimensions "down" they are from the body.

  8. Triadic pyramid - Wikipedia

    en.wikipedia.org/wiki/Triadic_pyramid

    The triadic pyramid remained a popular architectural form for centuries after the first examples were built. [15] The triadic form continued in use into the Classic Period, with later examples being found at Uaxactun, Caracol, Seibal, Nakum, Tikal and Palenque. [16] The Qʼumarkaj example is the only one that has been dated to the Postclassic ...

  9. DIKW pyramid - Wikipedia

    en.wikipedia.org/wiki/DIKW_Pyramid

    A standard representation of the pyramid form of DIKW models, from 2007 and earlier. [1] [2]The DIKW pyramid, also known variously as the knowledge pyramid, knowledge hierarchy, information hierarchy, [1]: 163 DIKW hierarchy, wisdom hierarchy, data pyramid, and information pyramid, [citation needed] sometimes also stylized as a chain, [3]: 15 [4] refer to models of possible structural and ...
