Visual explanation of the Golden Ratio formula, showing how a line segment is divided into two parts a and b such that the ratio of the whole to the longer part equals the ratio of the longer part to the shorter part, resulting in the golden ratio φ ≈ 1.618.

Diagram illustrating the Golden Ratio with a line segment PQ divided into parts a and b, showing the relationship a/b = (a+b)/a = 1.618... = φ, labeled with "Golden Ratio" and the Cuemath logo.
