Neliösuorakulmaiset

Neliösuorakulmaiset is a Finnish term that translates to "square rectangular" or more precisely, a specific type of rectangle. In geometry, a neliösuorakulmainen refers to a rectangle where the ratio of the length of its longer side to the length of its shorter side is the golden ratio, approximately 1.618. This specific proportion is known as the golden rectangle.

The golden ratio has been observed and utilized in art, architecture, and design for centuries, believed by some to possess aesthetically pleasing qualities. A golden rectangle can be constructed in several ways, often involving geometric constructions based on the properties of the golden ratio itself. If a square is cut from a golden rectangle, the remaining rectangle is also a golden rectangle. This self-similarity is a key characteristic.

While the term "neliösuorakulmainen" specifically denotes the golden rectangle, it's important to note that all golden rectangles are indeed rectangles. However, not all rectangles are golden rectangles. The defining feature is the precise mathematical ratio between their sides. The concept is primarily of interest in fields that explore mathematical aesthetics and proportional relationships.
