- how many faces, edges, and vertices are there in each platonic solid ?
- how can an icosahedron be inscribed in a cube ?
- how many faces can an equilateral deltahedron have ?
- what is another way to color the compound of 5 tetrahedra ?
- what is inside the compound of 5 cubes ?
- how can the compound of 5 octahedra be a stellation of a 20-faced icosahedron when 5*8=40 ?
- why do deltahedra have an even number of faces ?
- which Johnson solids are chiral ?
- which Johnson solids have more than one axis of symmetry ?
- can you make a zonohedron with 20 faces ?
- for which rhombi are there two parallelepipeds ?

Glossary
This page pertains to the parts and properties of polyhedra. Most of the entries have links to more detailed discussions.
The naming of individual polyhedra is discussed on its own separate page.

Knolling (W3)
Engl. "Knolling" ist eine Organisationsform in der Einzelteile exakt parallel oder im rechten Winkel zueinander angeordnet werden.
Benannt wurde sie nach der US-Designfirma "Knoll". Aber erst der dort angestellte Hausmeister brachte die Designer auf ihr Markenzeichen. Andrew Kromelow ordnete seine Werkzeuge auf allen möglichen Oberflächen im rechten Winkel an. Dies inspirierte den Künstler Tom Sachs und er kreiierte dafür den Spruch "Always be Knolling".
(E?)(L?) http://knolling.org/
Knolling is the process of arranging like objects in parallel or 90 degree angles as a method of organization.
(E1)(L1) http://books.google.com/ngrams/graph?corpus=0&content=Knolling
Abfrage im Google-Corpus mit 15Mio. eingescannter Bücher von 1500 bis heute.
Engl. "Knolling" taucht in der Literatur um das Jahr 1770 auf.

One-dimensional
Two-dimensional (W3)
(E?)(L?) http://www.wsu.edu/~brians/errors/one.html
Once upon a time most folks knew that "three-dimensional" characters or ideas were rounded, fleshed out, and complex and "two-dimensional" ones were flat and uninteresting. It seems that the knowledge of basic geometry has declined in recent years, because today we hear uninteresting characters and ideas described as "one-dimensional". According to Euclid, no object can be one-dimensional (of course, according to modern physics, even two-dimensionality is only an abstract concept). If you are still bothered by the notion that two dimensions are one too many, just use "flat".
