← HistoryWhich surveying inaccuracy increased when medieval Islamic engineers misapplied al-Khwarizmi's algebra?
A)Geodetic baseline misalignment
B)Horizontal angle distortion
C)Triangulation chain drift✓
D)Elevation contour deviation
💡 Explanation
Triangulation involved algebraic reduction; approximation errors caused CHAIN DRIFT because iterative angle propagation introduced accumulating offsets; therefore systematic displacement increased rather than local angle distortion, because geodetic measurements relied upon successive calculations.
