(1) The composition is concise and vivid, with strong three-dimensional sense. This is determined by the shape law of basic geometric figures. So the overall impression is clear and outstanding.
(2) They are significantly different from each other and easy for people to identify and identify.

Even if they are all straight lines, the combination and color of basic geometric figures are different and will show great differences. So it is not easy to be confused.
(3) standardized and easy to manufacture. The drawing of geometric figures, especially the drawing of basic geometric figures, has established standards and practices, and can be completed only by compasses and rulers. This brings great convenience to the manufacture of geometric figure trademarks. Once the drawing specifications are determined, geometric graphic trademarks of various sizes can be made uniformly.
