A '''shape''' is a [[graphics|graphical representation]] of an object's form or its external boundary, outline, or external [[Surface (mathematics)|surface]]. It is distinct from other object properties, such as [[color]], [[Surface texture|texture]], or [[material]] type.
In [[geometry]], ''shape'' excludes information about the object's [[Position (geometry)|position]], [[size]], [[Orientation (geometry)|orientation]] and [[chirality]].<ref name=Kendall/>
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 (geometry)|plane]]'', in contrast to ''[[solid figure|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 (mathematics)|surface]]'' (a [[two-dimensional space]]).
