  The Golden Ratio, also known as the Golden Section, represents a ratio frequently encountered in nature. It divides a line or length into two unequal parts, such that the ratio of the smaller part to the larger part is the same as that of the larger part to the whole. The rectangle with sides a and b, remaining after removing the square with side a, is similar to the original rectangle. The ratio a/b is denoted by φ, called the golden number, and also referred to as the golden ratio. φ is approximately 1.61803398875.
