The purpose of Triangle shall be to maintain a fraternity of engineers, architects, and scientists. It shall carry out its purpose by establishing chapters that develop balanced men who cultivate high moral character, foster lifelong friendships, and live their lives with integrity.
Triangle Fraternity has been on the campus of SD Mines for almost 100 years. We develop students into not only graduates, but into leaders, stewards, and Brothers. We take pride in our experiences on campus and in our community in the Black Hills. We welcome you to join us.
