Final answer:
Lateen sails were found in Egypt in the fifteenth century when Europe adopted new non-Western maritime technologies. When lateen sails were combined with square sails on European ships, they improved the ability to maneuver and navigate against the wind.
Step-by-step explanation:
In the fifteenth century, Europe experienced a navigational revolution with the adoption of new non-Western maritime technologies.
The lateen sail, a triangular sail that allowed ships to travel against the wind, was created by Arab sailors in the Middle East. Square sails, on the other hand, were more commonly used by Europeans.
However, when Europeans combined the lateen sail with square sails on three-masted ships, they could navigate confidently in any direction.
