yes, they are all geometric

http://en.wikipedia.org/wiki/Geometric_pattern
The pattern is a form, template, or model (or, more abstractly, a set of rules) which can be used to make or to generate things or parts of a thing, especially if the things that are created have enough in common for the underlying pattern to be inferred, in which case the things are said to exhibit the pattern. Pattern matching is the act of checking for the presence of the constituents of a pattern. The detection of underlying patterns is called pattern recognition. The question of how different patterns emerge is accomplished through the work of the scientific field of pattern formation. Patterns are also related to repeated shapes or objects, sometimes referred to as elements of the series. Some patterns (for example, many visual patterns) may be directly observable through the senses.

Some patterns are named. Simple decorative examples are stripes , zigzags, and polka-dots. Further examples include the regular tiling of a plane, echoes, and balanced binary branching.

all lines, circles, are all geometric patterns
including dots and stripes
