Which geometrical projection facilitated the construction of flat astrolabes during the Islamic Golden Age?

💡 Explanation

When mapping the celestial sphere onto a flat surface, stereographic projection was employed because it is conformal, preserving angles, which is crucial for accurate astronomical calculations. Therefore, stereographic projection facilitated astrolabe construction instead of gnomonic, orthographic, or equidistant projections due to angular fidelity.
