3D Shapes word list, defined
- CUBE /kjuːb/ · noun
- A solid three-dimensional figure with six equal square faces; also, the result of multiplying a number by itself twice (n × n × n). Related: block, solid, hexahedron.
- SPHERE /ˈsɪrəʊ/ · noun
- A three-dimensional shape where every point is equidistant from a central point. A sphere can be a ball, a globe, or a shape in space. Related: ball, globe, orb, circle.
- CYLINDER /ˈsɪl.ɪn.dər/ · noun
- A solid geometric figure with straight parallel sides and a circular or oval cross-section; more generally, any object shaped like this, such as the chamber of an engine in which a piston moves. Related: tube, drum, barrel, canister.
- CONE /koʊn/ · noun
- A solid or surface tapering smoothly from a flat circular base to a point (the apex); also, an object shaped like this, such as a traffic marker, ice-cream holder, or the fruit of certain conifers. Related: spire, taper, pyramid.
- PYRAMID /ˈpaɪəmɪd/ · noun
- A polyhedron with a square base and four triangular sides that meet at the apex, typically with a smooth surface and often used as a tomb for a pharaoh in ancient Egypt. A structure or shape resembling this, especially one that is narrow at the top and wider at the base. Related: tetrahedron, pyramidal, obelisk, monolith.
- PRISM /prɪzəm/ · noun
- A solid body with flat, usually triangular faces, typically with three pairs of equal and parallel sides, and with two pairs of opposite sides that are parallel to each other. A prism can also refer to a device that separates white light into its component colors, often used in optical instruments. Related: crystal, glass, lens, spectacle.
- TETRAHEDRON /tɛˈtɹəhɪdrɑn/ · noun
- A polyhedron composed of four triangular faces, six straight edges, and four vertex corners. In geometry, a tetrahedron is a three-dimensional shape with a triangular base and three triangular sides. Related: pyramid, trapezohedron, octahedron, dodecahedron.
- OCTAHEDRON /ɒktəˈhɛdrən/ · noun
- A polyhedron with eight plane faces, each of which is a triangle. In geometry, an octahedron is one of the five Platonic solids. Related: polyhedron, geometric shape, three-dimensional figure, solid.
- DODECAHEDRON /ˌdoʊdɛkəˈhiːdrən/ · noun
- A three-dimensional solid figure with twelve flat faces, each of which is a regular pentagon in the regular dodecahedron. Related: polyhedron, solid figure, twelve-sided solid, regular solid.
- ICOSAHEDRON /ˌaɪkəˈsædriːən/ · noun
- A polyhedron with 20 faces, each an equilateral triangle. In geometry, an icosahedron is one of the five Platonic solids. Related: polyhedron, geometric shape, three-dimensional figure, solid.
- VERTEX /ˈvɜːrtɪks/ · noun
- The point where two or more lines or planes intersect, or a point on a curve or surface. In geometry, a point that is one of the corners of a polygon. Related: corner, point, apex, intersection.
- EDGE /ɛdʒ/ · noun (also verb)
- The outside limit or boundary line of an object, surface, or area; also a sharp cutting side of a blade. Figuratively, it denotes a slight advantage over others. Related: brink, margin, border, rim.
