Which statement is true regarding spatial objects?

The statement that a point has zero dimensions is indeed true. In the context of spatial objects, a point is defined as a specific location in space that has no length, width, or height, effectively making it a zero-dimensional object.

To appreciate the dimensionality of various spatial objects, it’s crucial to understand their definitions. A line is commonly understood to be one-dimensional, characterized by having length but no width or height. A polygon, on the other hand, is typically considered two-dimensional as it occupies a plane—fittingly described by its length and width but having no height. When referring to three-dimensional shapes, such as cubes or spheres, these objects have all three dimensions: length, width, and height.

Thus, while examining the dimensional attributes of points, lines, and polygons, the assertion regarding the point correctly informs us of its unique characteristic of being a zero-dimensional entity, affirming why that statement is the correct one in this scenario.
