Which mechanism explains how medieval astronomers determined planetary positions using astrolabes?

💡 Explanation

Using astrolabes requires a stereographic projection because representing a 3D celestial sphere on a 2D plane preserves angles allowing for accurate angular measurements of celestial objects; therefore, astronomers could determine planetary positions rather than relying on direct parallax measures.
