Golden spiral - Wikipedia
A Fibonacci spiral approximates the golden spiral using quarter-circle arcs inscribed in squares derived from the Fibonacci sequence. A golden spiral with initial radius 1 is the locus of points of polar coordinates satisfying where is the Golden Ratio.
Fibonacci Sequence - Formula, Spiral, Properties - Cuemath
The Fibonacci spiral is a geometrical pattern that is derived from the Fibonacci sequence. It is created by drawing a series of connected quarter-circles inside a set of squares that are sized according to the Fibonacci sequence.
Fibonacci sequence - Wikipedia
In mathematics, the Fibonacci sequence is a sequence in which each number is the sum of the two preceding ones. Numbers that are part of the Fibonacci sequence are known as Fibonacci numbers, commonly denoted Fn.

THE FIBONACCI SEQUENCE, SPIRALS AND THE GOLDEN MEAN
THE FIBONACCI SEQUENCE, SPIRALS AND THE GOLDEN MEAN. The Fibonacci sequence exhibits a certain numerical pattern which originated as the answer to an exercise in the first ever high school algebra text. This pattern turned out to have an interest and importance far beyond what its creator imagined.

Spiral Leaf Growth. This interesting behavior is not just found in sunflower seeds. Leaves, branches and petals can grow in spirals, too. Why? So that new leaves don't block the sun from older leaves, or so that the maximum amount of rain or dew gets directed down to the roots.

Makes A Spiral. When we make squares with those widths, we get a nice spiral: Do you see how the squares fit neatly together? For example 5 and 8 make 13, 8 and 13 make 21, and so on. This spiral is found in nature! See: Nature, The Golden Ratio, and Fibonacci. The Rule. The Fibonacci Sequence can be written as a "Rule" (see Sequences and Series).
