The covering of a plane surface with geometric shapes without gaps or overlaps. While common in art and design, exactly repeating tilings are less easy to find in living things.Īlso called a ~. There are 17 wallpaper groups of tilings. ~s are patterns formed by repeating tiles all over a flat surface. A solid figure with 4 vertices, 6 edges and 4 (triangular) faces. Tetrahedron: A pyramid with a triangular base. ~: A pattern where polytopes are placed in a space so that the geometric figures do not overlap and no space is not covered for an arbitrarily large space. Probability based on thought experiments rather than a collection of data. Tiling of a plane with one or more shapes as a way of covering the plane with the shape(s) with no gaps or overlaps. Translation: A translation, also called a slide, is a geometrical movement in which a figure or shape is moved from each of its points the same distance and in the same direction. ~: Congruent plane figures/shapes that cover a plane completely without overlapping. This is done by projecting each solid onto a concentric sphere. Indeed, one can view the Platonic solids as the five regular ~s of the sphere. The three regular ~s of the plane are closely related to the Platonic solids. ![]() Ī ~ of the plane is a regular repeating pattern of one or more shapes that covers the entire plane. ~ is found in 1660 in The History of the Propagation and Improvement of Vegetables by Robert Sharrock (1630-1684): "Yet they, instead of those elegant ~s, are beautified otherwise in their site with as great curiosity.". Tetrahedron A polyhedron with four faces. ![]() ![]() The figure which is copied is commonly called the "fundamental region" ~ A filling up of a two-dimensional space by congruent copies of a figure that do not overlap. Theorem: A general statement that requires proof. Tetrahedron : A polyhedron with four faces one of the five Platonic solids that has four equilateral triangles as faces ( pyramid). The idea is that the design could be continued infinitely far to cover the whole plane (though of course we can only draw a small portion of it). Although Napoleon's theorem is not mentioned in the book, you can get a sense how this approach applies to other problems.Ī ~ is a design using one ore more geometric shapes with no overlaps and no gaps. Various plane ~s are discussed in a recent book Dissections: Plane & Fancy (Cambridge University Press, 1997) by Greg Frederickson from Purdue University. A terminating decimal will have a finite number of digits after the decimal point. In other words, a terminating decimal doesn't keep going. ![]() The ~ is a repeating pattern of figures that covers a plane without any gaps or overlaps. Examples of a ~ are: a tile floor, a brick or block wall, a checker or chess board, and a fabric pattern. the shapes must fit together without any gapsĪ tessellation is a repeated geometric design that covers a plane without any gaps or spaces.Ī ~ is a tiling over a plane with one or more figures such that the figures fill the plane with no overlaps and no gaps. ![]()
