Tessellation

Tessellation represents the systematic arrangement of shapes that completely cover a surface without leaving gaps or creating overlaps. This fundamental concept bridges mathematics, visual arts, and natural phenomena, forming the basis for countless patterns in both human design and the natural world.

Mathematical Foundation

Basic Principles

• Complete coverage of a plane
• No gaps between shapes
• No overlapping of shapes
• Regular polygons as basic units
• Symmetry groups governing arrangements

Types of Tessellation

1. Regular Tessellations

   • Use single type of regular polygons
   • Only three possible patterns:
     • Equilateral triangles
     • Squares
     • Regular hexagons

2. Semi-regular Tessellations

   • Combine multiple regular polygons
   • Must maintain vertex uniformity
   • Include Archimedean tilings

3. Irregular Tessellations

   • Use irregular shapes
   • Include Penrose tilings
   • Allow for more complex patterns

Natural Occurrences

Tessellation appears frequently in nature through:

• Honeycomb structures in beehives
• Crystal lattices in minerals
• Scale patterns on fish and reptiles
• Cell structures in living tissues
• Molecular arrangements in materials
