Is every shape in real life 3-D?

Answer 1

Not every shape in real life is 3-D; many shapes can be 2-D, such as drawings, photographs, or shadows. While physical objects we interact with are typically three-dimensional, concepts like geometric figures or patterns can exist in two dimensions. Additionally, certain shapes can exist in abstract contexts, such as mathematical representations or digital graphics. Thus, shapes can be both 2-D and 3-D depending on their context.
