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,[1] 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,"[2] 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.[3]
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
- hi julia and grace
- golf is the best..the world hsould be ruled my them
- the golden rectangle is crap and not real
Applications of the golden rectangle
- Some authors report that the dimensions of the façade of the Parthenon fits into a golden rectangle [4]
- 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.[5]
