The Bermuda Triangle is a hypothetical patch of ocean waters off the coast of North America, in the far north of the Atlantic. In fact, there is no actual agreement on the size, location or shape of the Bermuda Triangle. It is an imaginary territory, not defined by geographic or geological topography, but generally the most acceptable boundary is an unclear triangle, whose heads are at three points: Florida, the Greater Antilles (the most important tropical archipelago is Cuba), and the Bermuda Islands (a small archipelago administratively administered by Britain).
