🔍 Explanation:

- 2D shapes are flat and have only length and width (e.g., circle, triangle, rectangle).
- 3D shapes are solid and have length, width, and height (e.g., cube, cylinder, pyramid).
- Some shapes like "heart" are not strictly geometric but are often used in early learning to recognize common forms.
