Research Triangle, Raleigh

The Research Triangle, or simply The Triangle, are both common nicknames for a metropolitan area in the Piedmont region of North Carolina in the United States, anchored by the cities of Raleigh and Durham and the town of Chapel Hill, home to three major research universities: North Carolina State University, Duke University, and University of North Carolina at Chapel Hill, respectively. The nine-county region, officially named the Raleigh–Durham–Cary combined statistical area, comprises the Raleigh–Cary and Durham–Chapel Hill Metropolitan Statistical Areas and the Henderson Micropolitan Statistical Area. The "Triangle" name originated in the 1950s with the creation of Research Triangle Park, located between the three anchor cities and home to numerous high tech companies. ()
