Why do the shapes end in agon?

The suffix "agon" originates from the Greek Word "agon," which means contest or struggle. In geometry, terms like "polygon," "hexagon," and "octagon" refer to shapes defined by the number of sides or angles, with "agon" denoting the concept of "angle" or "corner." Thus, the use of "agon" highlights the competitive or structured nature of these shapes in relation to their angles and sides.
