A rectangle is a rectilinear polygon: its sides meet at right angles. A rectangle in the plane can be defined by five independent degrees of freedom consisting, for example, of three for position (comprising two of translation and one of rotation), one for shape (aspect ratio), and one for overall size (area).
In geometry, a golden rectangle is a rectangle whose side lengths are in the golden ratio, : +, which is : (the Greek letter phi), where is approximately 1.618.. Golden rectangles exhibit a special form of self-similarity: All rectangles created by adding a square to a side, or removing a square from an end, of a golden rectangle are golden rectangles as well.
A golden rectangle—that is, a rectangle with an aspect ratio of —may be cut into a square and a smaller rectangle with the same aspect ratio. The golden ratio has been used to analyze the proportions of natural objects and artificial systems such as financial markets, in some cases based on dubious fits to data. [8]
Mies van der Rohe. The Farnsworth House, designed by Ludwig Mies van der Rohe, has been described as "the proportions, within the glass walls, approach 1:2" [ 43] and "with a width to length ratio of 1:1.75 (nearly the golden section)" [ 44] and has been studied with his other works in relation to the golden ratio. [ 45]
The rectangular function (also known as the rectangle function, rect function, Pi function, Heaviside Pi function, [ 1] gate function, unit pulse, or the normalized boxcar function) is defined as [ 2] Alternative definitions of the function define to be 0, [ 3] 1, [ 4][ 5] or undefined. Its periodic version is called a rectangular wave .
Second moment of area. The second moment of area, or second area moment, or quadratic moment of area and also known as the area moment of inertia, is a geometrical property of an area which reflects how its points are distributed with regard to an arbitrary axis. The second moment of area is typically denoted with either an (for an axis that ...
In a graphical representation of the continuous uniform distribution function [()], the area under the curve within the specified bounds, displaying the probability, is a rectangle. For the specific example above, the base would be 16 , {\displaystyle 16,} and the height would be 1 23 . {\displaystyle {\tfrac {1}{23}}.} [ 5 ]
A dynamic rectangle is a right-angled, four-sided figure (a rectangle) with dynamic symmetry which, in this case, means that aspect ratio (width divided by height) is a distinguished value in dynamic symmetry, a proportioning system and natural design methodology described in Jay Hambidge 's books. These dynamic rectangles begin with a square ...
