A Golden Rectangle is a special type of rectangle where the ratio of its longer side to its shorter side is approximately 1.618, known as the Golden Ratio. This ratio is often denoted by the Greek letter phi (φ) and is considered aesthetically pleasing in art and architecture. When a square is removed from a Golden Rectangle, the remaining rectangle is also a Golden Rectangle. The concept of the Golden Rectangle has been used by famous artists and architects, including Leonardo da Vinci and Le Corbusier, to create visually harmonious compositions. It can be found in nature, such as in the arrangement of leaves and flowers, making it a fascinating subject in both mathematics and design.
