use of

geometry and repetition. The artist likely used basic geometric shapes, such as triangles, squares, and hexagons, and arranged them in a repetitive pattern to create the tessellation. The artist may have also manipulated the shapes, such as by rotating or flipping them, to further enhance the repetition. Additionally, the artist likely paid attention to the color and texture of the shapes to create a visually appealing composition.
