For students at Level 4, grasping the concepts of shapes lays a foundation for more advanced studies in geometry, physics, architecture, and even computer science.

What Are Shapes? Defining the Building Blocks of Geometry

At its core, a shape is a geometric figure or form that occupies space. Shapes can be two-dimensional (2D) or three-dimensional (3D), each with distinct properties and characteristics.

2D Shapes (Plane Figures)

• Definition: Flat figures with length and width.
• Examples: Circles, squares, triangles, rectangles, pentagons, hexagons, and more.

3D Shapes (Solid Figures)
