Which mechanism prevented collapse in Inca polygonal stonework walls?

💡 Explanation

Interlocking stone polygonal geometry increases stability because frictional force resists slippage under stress; therefore, the result is enhanced structural integrity, rather than relying on mortar or external support because these solutions offered less internal cohesion against seismic stress.
