Explanation:
1. Three-dimensional shapes are referred to as "form" in art and design terminologies.
2. In art, form refers to objects that have height, width, and depth, giving them a three-dimensional quality.
3. These shapes are not flat like those found in two-dimensional artworks but have volume and occupy space.
4. Examples of three-dimensional forms include cubes, spheres, pyramids, and cylinders.
5. Understanding form is essential in creating realistic and dynamic artworks, as it adds depth and dimension to compositions.
Therefore, the term that best describes three-dimensional shapes is "form."
