Geometric shapes are the flat or solid forms we see in the world — made from lines, angles, and curves.
Shapes can be 2D (flat) like circles and triangles, or 3D (solid) like cubes and cylinders.
2D Shapes: triangle, rectangle, pentagon
3D Shapes: cube, sphere, cone, prism
Recognizing shapes helps us understand design, space, structure, and how things fit together in real life — like in buildings, packaging, or art.
