A hexagon is a polygon with six sides. The word "hexagon" is derived from the Greek words "hexa" meaning six and "gonia" meaning angles.

To visualize a hexagon, imagine a shape with six straight sides and six angles. Each side of a hexagon is called an edge, and the point where two edges meet is called a vertex.

Here's an example of a hexagon:

Hexagons can be found in various real-life objects and structures. For instance:

• Honeycombs: The cells in a honeycomb are hexagonal in shape, allowing bees to efficiently use space.
• Stop signs: The red octagonal shape of a stop sign is formed by combining two hexagons.
• Snowflakes: Snowflakes often have hexagonal symmetry due to the arrangement of water molecules during crystallization.

Hexagons also have interesting mathematical properties. For example, the sum of the interior angles of a hexagon is always 720 degrees. Additionally, a regular hexagon (where all sides and angles are equal) can be divided into equilateral triangles.
