"More deltoidal" can be described using several synonyms. Some of these include triangular, pyramidal, cone-shaped, diamond-shaped, and trapezoidal. Each of these words evokes an image of a shape with a similar structure to a deltoid, which is a four-sided figure with two parallel sides. Using synonyms to describe the shape can allow for clearer communication and a better understanding of what is being discussed. For example, if one is referring to a building with a deltoidal shape, saying it is "pyramidal" or "cone-shaped" may be more descriptive and informative to the listener or reader.
