- a proportion based on the golden ratio (sense ): held to be detectable in nature, classical architecture, Renaissance art, etc. and purported to be aesthetically pleasing to the eye (Ex.: in the line ACB, if AB is to AC as AC is to CB)
- golden ratio (sense )
A ratio, observed especially in the fine arts, between the two dimensions of a plane figure or the two divisions of a line such that the smaller is to the larger as the larger is to the sum of the two, a ratio of roughly three to five. Also called golden ratio .
The ratio between two numbers a and b chosen such that the ratio of a to b is equal to the ratio of a+b to a. Its value is approximately 1.618. Shapes with proportions equal to the golden section are observed especially in the fine arts and in architecture, as between the two dimensions of a plane figure such as a rectangle. The ratio between consecutive numbers in a Fibonacci sequence approximates the golden section with increasing precision as the series progresses. Also called golden mean
