Final answer:
The note mentioning the triangular arrangement of the figures in the statue is most relevant to the structure of the statue, as it describes the statue's physical composition.
Step-by-step explanation:
The most relevant note to the structure of the statue would likely be the one about the arrangement, specifically that 'Three figures are arranged in a triangle, suggesting an apex with two supporting angles.' This note speaks directly to the physical composition and layout of the statue. The points about symbolism and attire are important for understanding thematic elements but are less relevant to the statue's structure. Similarly, the point of view noted as well as the connection with architecture provided by Beth offer context to how the statue interacts with its space, but do not address its structure directly. The arrangement note best explains how viewers perceive the statues in relation to one another and in space, which is essential to understanding the physical configuration of the monument.
