shape

A shape is a graphical representation of an object's form or its external boundary, outline, or external surface. It is distinct from other object properties, such as color, texture, or material type.
In geometry, shape excludes information about the object's position, size, orientation and chirality.
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).
