Explanation:
The triangular trade was common in Europe during the colonies time and it consisted in trades on three different parts of the world, in the European part they´d send finished goods, like mirrors, sugar, textiles, or other products and they´d exchange them for slaves, that later would be traded in America for primary goods, like cotton, sugar canes or precious metals, that then´ would be traded back to Europe.
