Golden ratio

Definition

The golden ratio is a mathematical ratio, approximately 1.618, that is often found in nature and has been used in art and architecture to create aesthetically pleasing compositions. This ratio, symbolized by the Greek letter phi (φ), establishes a proportional relationship where a line is divided into two parts such that the whole length divided by the longer part is equal to the longer part divided by the shorter part. The use of the golden ratio during the Renaissance reflects the period's emphasis on balance, harmony, and natural beauty.
