What are the characteristics of geometric patterns in ancient painted pottery patterns?

Geometric patterns are made up of four main elements: straight lines, diagonal lines, triangles, points and wavy lines. Majiayao culture mostly integrates the images of animals and plants into geometric patterns through evolution, and adopts a large number of vortex patterns, wave patterns, parallel provisions, large round patterns and so on. And combine all kinds of individual geometric patterns into double-sided or four-sided continuous patterns to adapt to the circular shape of the utensils, form certain structural rules, and produce symmetrical, balanced, continuous, end-to-end and colorful aesthetic effects.
