Our History, Purpose & Code of Ethics



Triangle is a nationally-reaching organization, with 35 chapters in 25 states and over 20,000 living alumni. While we are proud part of this large community, Triangle started here at Illinois. In 1907, sixteen undergraduate civil engineering students sought to create an organization that brough engineers together. Although it was initially limited to civil engineering, today Triangle is a community of male engineers, architects, and scientists brought together to achieve a common purpose. The site of the original chapter house is where our current home stands today.


"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."
