Water (H₂O) $Molecule Geometry$ and the π/2 Equilibrium

This paper presents the exact, error-free mathematical formulation of the intramolecular angular equilibrium for the water molecule (H₂O), establishing a framework where the structural ratios perfectly converge to the mathematical constant π/2. By accounting for scale transitions and natural quantum-mechanical fluctuations as the default physical baseline, we isolate the exact system angles that ensure absolute trigonometric consistency without relying on empirical approximations or fabricated variables.
