Humans build hexagons with equal-sided shapes that enclose each vertex with two other sides of exactly the same size and two equal interior angles. This special structure results from its internal rigidity and gives them structural stability against most types of load forces, while the interior of the enclosed space maintains perfect uniformity as the surface of each triangular shape always meets a right angle and does so along three points at any time that a vertical force acts on any edge, it will maintain this position, resisting collapse and preventing damage to internal content by spreading stresses evenly.
