A shape is created when a line is enclosed. Shape is one of the seven elements of art and it has a variety of uses in the creation of art. Shape is a two-dimensional area that is defined by a change in value or some other form of contrast.
All shapes are two-dimensional, meaning that they have only length and width.
All shapes will fall into one of two categories. Geometric shapes or regular shapes are easy to recognize. Math can be used to find information about these shapes and these shapes generally have a specific name associated with them. Examples include: circle, triangle, square, and trapezoid.
Organic or freeform shapes are shapes that seem to follow no rules. Organic shapes generally do not have a name associated with them and are typically not man-made.
We can learn to see the world around us as shapes. Recognizing the shapes that we see will lead to improved drawing and painting.
