This article introduces the Angular Logarithmic Base Theorem, a mathematical relationship connecting angles and proportions through geometry. Expressed by the equation tan(γ) = √(DB / AD), the theorem reveals a direct link between an angle and the logarithmic base governing the ratio between two line segments. This elegant formulation allows for intuitive and visual modeling of growth, scale, visual hierarchy, and spatial organization. Its applications span music theory, design, architecture, urban planning, data visualization, and more. By converting proportional relationships into angular values, this theorem offers a new geometric lens through which to understand harmonic and exponential structures.
