The book is heavily illustrated, [4] and describes geometric patterns in the carvings, textiles, drawings and paintings of multiple African cultures. Although these are primarily decorative rather than mathematical, Gerdes adds his own mathematical analysis of the patterns, and suggests ways of incorporating this analysis into the mathematical curriculum.

Key pattern is the generic term for an interlocking geometric motif made from straight lines or bars that intersect to form rectilinear spiral shapes. [ 1 ] [ 2 ] [ 3 ] According to Allen and Anderson, the negative space between the lines or bars of a key pattern “resemb[es] the L- or T-shaped slots in an ordinary key to allow it to pass the ...
The meander is a fundamental design motif in regions far from a Hellenic orbit: labyrinthine meanders ("thunder" pattern [3]) appear in bands and as infill on Shang bronzes (c. 1600 BC – c. 1045 BC), and many traditional buildings in and around China still bear geometric designs almost identical to meanders.
A form is an artist's way of using elements of art, principles of design, and media. Form, as an element of art, is three-dimensional and encloses space. Like a shape, a form has length and width, but it also has depth. Forms are either geometric or free-form, and can be symmetrical or asymmetrical.
Class III: {3,q+} b,c have nonzero unequal values for b,c, and exist in chiral pairs. For b > c we can define it as a right-handed form, and c > b is a left-handed form. Subdivisions in class III here do not line up simply with the original edges.

Patterned ground is the distinct and often symmetrical natural pattern of geometric shapes formed by the deformation of ground material in periglacial regions. It is typically found in remote regions of the Arctic , Antarctica , and the Outback in Australia , but is also found anywhere that freezing and thawing of soil alternate; patterned ...
