A tessellation is a pattern that covers an infinite plane with repeated geometric shapes, leaving no gaps and having no overlaps. Connects geometry to art, architecture, crystallography, and spatial reasoning about repeating patterns.
Definition
A tessellation is a pattern that covers an infinite plane with repeated geometric shapes, leaving no gaps and having no overlaps.
💡 Intuition
Like a bathroom floor tile pattern that fits together perfectly and could extend forever in all directions.
🎯 Core Idea
A regular polygon tessellates the plane only if its interior angle evenly divides 360°; only triangle, square, and hexagon work.
Example
🌟 Why It Matters
Connects geometry to art, architecture, crystallography, and spatial reasoning about repeating patterns.
💭 Hint When Stuck
Check angle sums around each vertex to confirm full 360^circ coverage.
Related Concepts
🚧 Common Stuck Point
Students overlook tiny gaps or overlaps in repeated patterns.
⚠️ Common Mistakes
- Assuming every regular polygon tessellates
- Ignoring local vertex angle sums
