While the Arabs are generally credited with this, their boats were often constructed from the wood found in the forests of India. So far, it's hard to say.
No the Caravel had a lateen and a square sail and was steered by rudders. The lateen sail aloud it to sail against the wind
A caravel is a small, highly maneuverable sailing ship developed in the 15th century by the Portuguese. The lateen sails gave it speed and the capacity for sailing to windward.
The Caravel.
The lateen sail, which allowed tacking into the wind, the block and tackle, which allowed the raising of large sails with less manpower, the compass and the sextant. I don't know which three your teacher wants, but these four were critical.
Fast and easily maneuverable, the caravel was developed around 1450- and quickly became the preferred stlyle of vessel for the Portuguese exploreres. It had a shallow keel, so it could sail upriver (and explore!) in the shallow coastal waters. It could be rigged with lateen (triangular) sails, so it could sail closer to the wind. With the more standard square sails rigged, it was very fast. So- with it's agility, economy, speed, power, and versatility, it's small wonder Christopher Columbus used them in 1492.
The lateen sail was invented around 100.

A type of sail
It is called the lateen sail.
in polynesia
A three sided sail is known as a Lateen sail or also a triangular sail. With a four sided sail one is only able to sail against the wind, but with a Lateen sail it is possible to sail more directly into the wind.
The Arabs used them
The lateen is believed to have been used in the Eastern Mediterranean as early as the 2nd Century ce (common ear). The effective use by the Arabs caused it's rapid spread through the Mediterranean. The lateen sail was so popular because its ability to sail into the wind. Prior to the lateen a majority of sea vessels used square sails (which one can imagine wouldn't sail into the wind very effectively). The lateen made up a majority of ship sails during the Age of Discovery (When Columbus discovered the Americas). The lateen made it possible to sail faster, farther, and more efficiently. An elite ship during the Age of Discovery was the caravel, its elite status can be attributed to how effectively it utilized the lateen sail.
