Final answer:
Triangular designs can be used in decorating to create movement, visual interest, and balance in display purposes.
Step-by-step explanation:
Triangular designs can be used in decorating to the best advantage for display purposes by creating a sense of movement, adding visual interest, and creating balance. For example, a triangular arrangement of objects can create a flow that leads the viewer's eyes around the display. Triangles can also be used to break up large areas of space or to highlight a particular object or focal point. Additionally, by placing the most important part of a display at one of the four intersections of a triangular composition, it creates balance and makes the display more visually pleasing.
