The document discusses different types of balance in design including symmetrical balance where both sides are similar, asymmetrical balance where the sides are different but still balanced, and radial balance where elements are arranged around a central point. It also defines principles of design such as movement, which is the path the viewer's eye takes through a work of art; proportion, which is the feeling of unity from all parts relating well; and pattern, variety, unity, rhythm, and emphasis, which relate to repeating elements, multiple elements to engage the viewer, harmony between parts, mood, and the focal point that catches the viewer's attention.
