Gaussian curve with a two-dimensional domain Many shapes have metaphorical names , i.e., their names are metaphors : these shapes are named after a most common object that has it. For example, "U-shape" is a shape that resembles the letter U , a bell-shaped curve has the shape of the vertical cross section of a bell , etc.
Two clusters of faces of the bilunabirotunda, the lunes (each lune featuring two triangles adjacent to opposite sides of one square), can be aligned with a congruent patch of faces on the rhombicosidodecahedron. If two bilunabirotundae are aligned this way on opposite sides of the rhombicosidodecahedron, then a cube can be put between the ...

A Jerusalem cube is a fractal object first described by Eric Baird in 2011. It is created by recursively drilling Greek cross-shaped holes into a cube. [15] [16] The construction is similar to the Menger sponge but with two different-sized cubes. The name comes from the face of the cube resembling a Jerusalem cross pattern. [17]
The cube is non-composite polyhedron, meaning it is a convex polyhedron that cannot be separated into two or more regular polyhedrons. The cube can be applied to construct a new convex polyhedron by attaching another. [62] Attaching a square pyramid to each square face of a cube produces its Kleetope, a polyhedron known as the tetrakis ...
The capsids of some viruses have the shape of geodesic polyhedra, [1] [2] and some pollen grains are based on geodesic polyhedra. [3] Fullerene molecules have the shape of Goldberg polyhedra . Geodesic polyhedra are available as geometric primitives in the Blender 3D modeling software package , which calls them icospheres : they are an ...

A small, most often dome-like, structure on top of a building. Cyma A projecting moulding whose edge forms an S-curve. The two major types of cyma are the cyma recta, in which the upper curve is concave, and the cyma reversa (also known as the ogee), in which the lower curve is concave. [22] Cyrto-style A circular projecting portico with ...
