Why was the trade route of rum slaves and sugar and molasses the triangular trade?

The triangular trade was a transatlantic system that connected Europe, Africa, and the Americas through the exchange of goods and enslaved people. Ships left Europe loaded with manufactured goods, which were traded in Africa for enslaved individuals. These enslaved people were then transported to the Americas to work on plantations producing sugar and molasses, which were then shipped back to Europe. This cyclical trade formed a triangle, with each leg representing a different part of the trade network.
