Golden Ratio Pronunciation: /ˈɡoʊl.dən ˈreɪ.ʃi.oʊ/ (GOHL-dun RAY-shee-oh)
Definition: A mathematical ratio, approximately 1.618:1, that is found by dividing a line into two parts so that the longer part divided by the shorter part is equal to the whole length divided by the longer part. Symbolized by the Greek letter φ (phi), the Golden Ratio appears in art, architecture, and nature due to its aesthetically pleasing proportions.
Example: The Parthenon’s façade and many Renaissance paintings are believed to use the Golden Ratio to achieve harmonious and visually appealing compositions.
