Golden Ratio. The golden ratio (symbol is the Greek letter phi shown at left) is a special number approximately equal to 1.618. It appears many times in geometry, art, architecture and other areas.
In mathematics, two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities. The figure on the right illustrates the geometric relationship. Expressed algebraically, for quantities a and b with a > b > 0, a + b a = a b = def Ï, {\displaystyle {\frac {a+b}{a}}={\frac {a}{b}}\ {\stackrel {\text{def}}{=}}\ \varphi,} where the Greek letter phi ( Ï {\displaystyle \varphi } or Ï {\displaystyle \phi } ) represents the golden ...
