Golden Angle: 137.5° Defined by the Golden Ratio's Circle Division — E8 Intelligence Research

FINDING: Golden angle defined as angular division of circle by golden ratio, yielding approximately 137.5° (or 222.5° for the complementary arc). | MATH: Golden angle \( φ = 360^∘ × (1 - 1/φ) = 360^∘ / φ^2 ≈ 137.507764^∘ \), where \( φ = (1+√5)/2 ≈ 1.6180339887 \). Also expressed as \( φ = 360^∘ × (2 - φ) \). | CONNECTION: Directly links to golden ratio \( φ \) and its reciprocal \( 1/φ ≈ 0.618 \). The ratio of the two arcs (major/minor) equals \( φ \). No explicit base-60 or crystallographic symmetry mentioned in these sources, but the angle appears in phyllotaxis and spiral patterns, which relate to 5-fold symmetry (icosahedral/crystallographic). | DEPTH: 6 — Fundamental geometric constant derived from golden ratio, but the provided sources are introductory; no deeper base-60 or lattice connection extracted.
