The formal name for an equilateral triangular design in floral arrangement is known as a symmetrical design. This design features equal balance and proportion on either side, creating a harmonious composition. The use of an equilateral triangle as the basis for this arrangement allows for stable visual balance, which is a key characteristic of symmetry. This design typically involves placing flowers and foliage in a way that reflects this balance, ensuring that elements are evenly distributed around a central axis. This approach not only enhances the aesthetic appeal but also conveys a sense of order and elegance, making it a foundational concept in floral design.

The other choices do not apply to this type of floral arrangement. Asymmetrical design, for instance, focuses on creating a balance that is visually interesting but not identical on both sides, while a round design is more circular and not specifically triangular. Intermediate colors refer to color theory and are unrelated to the structural aspects of floral arrangements. Understanding these distinctions helps clarify why symmetrical design is the correct answer in this context.
