The document discusses mandalas, circular designs that represent wholeness. Mandalas have radial symmetry, with elements like rays or shapes that are equal in size, shape, and color extending outward from a central point. Examples of radial symmetry can be seen in nature like flowers, snowflakes, and wheels. The basic structure of a mandala is a circle with a center, called radial balance. Mandalas can also be seen in architecture and are created by various artists. Students are instructed to make a radial symmetry collage by cutting and arranging photos in a circular pattern.
