Discovering Shapes

Geometry is all about shapes and their properties. You see shapes everywhere: in buildings, signs, and nature!

Common 2D Shapes

  • Square: 4 equal sides, 4 right angles
  • Rectangle: Opposite sides equal, 4 right angles
  • Triangle: 3 sides, 3 angles
  • Circle: Round, no sides or corners

Common 3D Shapes

  • Cube: Like a dice, 6 equal square faces
  • Sphere: Like a ball, perfectly round
  • Cylinder: Like a can, 2 circles and a curved side

Why Learn Shapes?

Shapes help you understand the world, solve puzzles, and create art!

Examples

  • Identifying a stop sign as an octagon.

  • Rolling a soccer ball (a sphere) on the field.

In a Nutshell

Geometry is the study of shapes all around us.
