Why Do Shapes Tile Surfaces Perfectly?

Shapes can tile a surface if they fit together perfectly with no gaps or overlaps. Imagine you have squares like floor tiles, each one fits snugly next to the others, just like building blocks. But if you try using pentagons, some might leave small spaces in between. It all depends on how sharp or curved the sides of the shape are.
