The book provided definitions for circumference, diameter, and radius, along with the definition of volume. [28] The Han dynasty (202 BC – 220 AD) period of China witnessed a new flourishing of mathematics. One of the oldest Chinese mathematical texts to present geometric progressions was the Suàn shù shū of 186 BC, during the Western Han era.
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.
Tilings, or tessellations, have been used in art throughout history. Islamic art makes frequent use of tessellations, as did the art of M. C. Escher. [136] Escher's work also made use of hyperbolic geometry. Cézanne advanced the theory that all images can be built up from the sphere, the cone, and the cylinder. This is still used in art theory ...
In painting, photography, graphical perspective and descriptive geometry, a picture plane is an image plane located between the "eye point" (or oculus) and the object being viewed and is usually coextensive to the material surface of the work. It is ordinarily a vertical plane perpendicular to the sightline to the object of interest.
A figure is a representation including both shape and size (as in, e.g., figure of the Earth). A plane shape or plane figure is constrained to lie on a plane, in contrast to solid 3D shapes. A two-dimensional shape or two-dimensional figure (also: 2D shape or 2D figure) may lie on a more general curved surface (a two-dimensional space).

Letras y figuras (Spanish, "letters and figures") is a genre of painting pioneered by José Honorato Lozano during the Spanish colonial period in the Philippines. The art form is distinguished by the depiction of letters of the alphabet using a genre of painting that contoured shapes of human figures, animals, plants, and other objects called ...
Composite art depicts a figure composed in whole or part of different creatures, including human beings, animals, birds, reptiles, insects, or dinosaurs such as Brontosaurus. [3] The origin of the style is unknown and debated by scholars. [4] Composite art has a history in two prominent traditions – Hindu and Mughal.
