What describes the balance achieved when the arrangement is equal on both sides?

Bilateral symmetry refers to a type of balance where both sides of a design or arrangement mirror each other, creating a sense of harmony and stability. In this context, when an arrangement has equal elements and visual weight on both sides, it creates a cohesive and balanced look. This symmetry can be seen in various design applications, such as in furniture placement, architectural features, or decor styles, where matching elements are intentionally used to enhance aesthetic appeal.

Dynamic balance, on the other hand, involves a more active feel with elements that are not identical but are arranged in a way that creates visual interest and energy. Proportional balance relates to the size and scale of elements rather than their placement, and static balance implies stability but does not specifically address the symmetry in arrangement. Each of these terms has its own distinct meaning and application within the realm of design.
