Terms & Definitions:
Balance- The equal distribution of visual weight or eye attraction on either side of a compositions's center.
Visual Weight- determined by an object's size, value, texture, & distance from the center.
Symmetrical- looks exactly the same on each side; identical elements distributed on wither side of a vertical axis in the center of the composition.
Approximate Symmetry- 2 sides are similar enough to imply a vertical central axis, and varied just enough to challenge you to identify the differences.
Asymmetrical- artist achieves the feeling of equally distributed visual weight with figures and objects that are different; it can still be balanced.
Radical- results from the repetitive placement of two or more identical or very similar elements around a central point. The elements of design come out (radiate) from a central point. This occurs frequently in nature growth patterns, architecture, or manufactured items.

Asymmetrical – this artwork is asymmetrical because it has the feeling of equal weight on both sides.
Radial – this piece of artwork is Radial because it had a center point

Symmetrical-this artwork is symmetrical, because it is the same on both sides.

Radial – this piece of artwork is Radial because it had a center point.
