Golden rectangle
From Wikipedia, the free encyclopedia
A golden rectangle is a rectangle whose side lengths are in the golden ratio, 1:φ, that is, approximately 1:1.618.
A distinctive feature of this shape is that when a square section is removed, the remainder is another golden rectangle, that is, with the same proportions as the first. Square removal can be repeated infinitely, which leads to an approximation of the golden spiral.
According to Mario Livio, since the publication of Luca Pacioli's Divina Proportione in 1509,<ref>Pacioli, Luca. De divina proportione, Luca Paganinem de Paganinus de Brescia (Antonio Capella) 1509, Venice.</ref> when "with Pacioli's book, the Golden Ratio started to become available to artists in theoretical treatises that were not overly mathematical, that they could actually used,"<ref name="livio">Livio, Mario (2002). The Golden Ratio: The Story of Phi, The World's Most Astonishing Number. New York: Broadway Books. ISBN 0-7679-0815-5.</ref> many artists and architects have proportioned their works to approximate the form of the golden rectangle, which has been considered aesthetically pleasing. The proportions of the golden rectangle have been observed in works predating Pacioli's publication.<ref>Van Mersbergen, Audrey M., Rhetorical Prototypes in Architecture: Measuring the Acropolis with a Philosophical Polemic, Communication Quarterly, Vol. 46, 1998 ("a 'Golden Rectangle' has a ratio of the length of its sides equal to 1:1.61803+. The Parthenon is of these dimensions.")</ref>

[edit] Constructing a golden rectangle

- Construct a simple square
- Draw a line from the midpoint of one side of the square to an opposite corner
- Use that line as the radius to draw an arc that defines the height of the rectangle
- Complete the golden rectangle
[edit] Applications of the golden rectangle
- Some authors report that the dimensions of the façade of the Parthenon fits into a golden rectangle <ref>Hemenway, Priya – Divine Proportion pp101, Sterling Publishing, ISBN 1-4027-3522-7</ref>
- Experts in the field of book design, describe the use of the golden rectangle in medieval book designs
- Le Corbusier's 1927 Villa Stein in Garches feaures a rectangular ground plan, elevation, and inner structure that are closely approximate to golden rectangles.<ref>Le Corbusier, The Modulor, p. 35, as cited in Padovan, Richard, Proportion: Science, Philosophy, Architecture (1999), p. 320.
