When referring to shapes with five sides, the term "pentagonal" is commonly used. However, there are also several synonyms that can be used to describe something that is more pentagonal in shape. For instance, "polygonal" is often used to refer to any shape that has multiple sides. "Pentagrammic" is another term used to describe shapes with five sides, but specifically ones that are arranged in a star-like pattern. "Five-sided" is a more straightforward yet effective way to describe something that is, in fact, pentagonal in shape. Finally, "quintangular" is a word that can be used to describe shapes that have five angles or five corners.
