symmetry

• a balanced similarity found on opposite sides of a dividing line around a center point

Tessellation

• a repeating pattern of shapes that fit together without gaps, over lapse, or space

golden ration

fractal

• detailed pattern that looks similar at any scale and repeats itself overtime

• simple shapes multiplying over time yet maintaining the same pattern

• snowflakes, tree branching, lightning, ferns

spiral

• a curved pattern that focuses on a center point and a series of circular shapes that revolve around it

• pinecones, some shells, pineapples, hurricanes

Voronoi pattern

• is a way of dividing space into regions based on how close things are to each other

• it helps shows how nature likes to be efficient, meaning it likes to use least amount of space and energy

• giraffes skin, puzzles

Fibonacci sequence

• a numerical pattern found in nature and mathematics, where each number is the sum of the two preceding ones

• named after the Italian mathematician Leonardo Fibonacci of Pisa, who introduced it in 1202, creates a mathematical pattern found in nature
