Hexagon
A hexagon is a polygon with 6 sides and 6 corners (vertices). Like regular triangles and squares, hexagons fit together without gaps. This is known as a tessellation. Because of this, they are often used for tiling floors. They are also quite common in nature. For example, the honeycombs in a beehive are hexagons.
