A flat shape with six straight sides and six angles, all of equal length and measure in a regular hexagon.
From Greek 'hex-' (six) and 'gonia' (angle). The term was used by ancient Greek mathematicians like Euclid to describe this geometric form, which appears frequently in nature.
Honeybees build hexagonal cells in their hives because it's the most efficient shape—hexagons fit together with no wasted space and use less wax than any other shape, which is why bees are basically nature's engineers.
