In the ancient world the square sail on "square rigged ships" was employed universally in the Mediterranean on the seagoing ships of the Egyptians, Phoenicians, Greeks and Romans. In Hellenistic and Roman times a spritsail (triangular sails) was sometimes set on a small raking foremast, known as an artemoon, in order to sail with a beam wind.
"Square-riggers" have primarily square sails, but the jib sails are triangular.

Caravels were a type of small, highly maneuverable sailing ship developed by the Portuguese in the 15th century. They were better than the ships they replaced, such as cogs and carracks, because they had a more streamlined hull design, allowing for greater speed and agility. Caravels also had triangular lateen sails that could catch wind from different directions, enabling them to sail closer to the wind and explore new trade routes more efficiently.
Well, back then people used the traditional square sails. So when the Caravel was built they used triangular sails instead of the traditional square sails which made the ship able to sail against the wind.
