Key Points

This research aims to demonstrate how the golden ratio is geometrically encoded in the structure of regular pentagons.
Analytical exploration of the 36°-72°-72° isosceles triangle
Derivation of relationships involving the golden ratio using trigonometry
Examination of historical mathematical connections to ancient Sumerian/Babylonian systems.
Established that the diagonal-to-side ratio of a regular pentagon equals the golden ratio (φ ≈ 1.618)
Showed that relationships involving secants and angles (36° and 72°) are encoded in the pentagon's geometry
Connected the geometric properties of pentagons to quasicrystals and crystallography.

We only have this paper's title and publication details.

Finding the geometric coding of the golden ratio in regular pentagons reveals mathematical connections to ancient mathematics.
