A shape is one of the seven elements of art. When defining it within the study of art, shape is an enclosed space, the boundaries of which are defined by other elements of art (i.e.: lines, colors, values, textures, etc.).
Shapes are limited to two dimensions: length and width.
GEOMETRIC SHAPES -
-- circles, rectangles, squares, triangles and so on -- have the clear edges one achieves when using tools to create them.
have natural, less well-defined edges (think: an amoeba, or a cloud).
types of geometric shapes: circle, oval, square, rectangle, triangle, trapezoid, parallelogram, pentagon, hexagon, and octagon.
Everything is ultimately a SHAPE, so you must always think in terms of how the various elements of design are creating shapes, and how those shapes are interacting.
