The simplest kind of symmetry. It can also be called mirror symmetry because an object with this symmetry looks unchanged if a mirror passes through its middle.
Rotational symmetry around a fixed point known as the center. Images with more than one lines of symmetry meeting at a common point exhibits a radial symmetry.
Never-ending patterns. The beauty of fractals is that their infinite complexity is formed through the repetition of simple equations. These repeating patterns are displayed at every scale.
A curved pattern that focuses on a center point and a series of circular shapes that revolve around it. Examples of spirals are pine cones, pineapples, hurricanes. The reason for why plants use a spiral form like the leaf picture below is because they are constantly trying to grow but stay secure.
