A golden rectangle is a rectangle with side lengths that are in the golden ratio (about 1:1.618). This article also explains how to construct a square, which is needed to construct a golden rectangle.

A golden rectangle is a rectangle with sides in the ratio of the golden ratio, which is an irrational number often denoted by phi. Learn how to construct a golden rectangle using Euclid's method, and explore its relation to the golden spiral, the golden triangle and other geometric shapes.

The golden ratio (φ) is a mathematical constant that relates the lengths of two quantities in a ratio of 1:1.618. Learn about its properties, history, and how it appears in nature, art, and geometry.

Learn about the Golden Ratio, an irrational number with a special property of being equal to its own reciprocal and successor. Discover how it relates to the Fibonacci Sequence, a series of numbers that appears in nature and art.

Learn what the golden ratio is, how to calculate it, and why it appears in geometry, art, and nature. Explore the properties, powers, and Fibonacci sequence related to the golden ratio.

A golden rectangle is a rectangle whose side lengths are in the golden ratio, approximately 1.618:1. It is often considered aesthetically pleasing and appears frequently in art and architecture.

The golden rectangle R, constructed by the Greeks, has the property that when a square is removed a smaller rectangle of the same shape remains. Thus a smaller square can be removed, and so on, with a spiral pattern resulting.
