The Purdue Triangle Chapter House at 103 University Street

Triangle is a national social fraternity for engineers, architects and scientists that was founded in 1907 at the University of Illinois. Triangle's 28 nationwide chapters, 24,000 alumni, and 97 years of history contribute to our rich traditions.

Because we limit our membership to students majoring in engineering, architecture and the sciences, Triangle is unique in the North-American Interfraternity Conference. Limiting our membership to these majors draws together outstanding men with similar course work and career goals. Our national list-serves and message boards allow our alumni to share openings at their companies, in some cases before the jobs are made known to the general public.

Triangle is serious about scholarship. Preparing yourself for your future career and achieving academic success are your primary goals at Purdue. Even so, social and athletic participation provides an enhancement to your busy and challenging college curriculum.

Many people ask, "What are Triangle's Greek letters?" Unlike most other social fraternities, we do not use a Greek letter name. This is one point that makes Triangle stand out in contrast to other fraternities on the Purdue campus. Triangle is easy to recognize as the only national fraternity for students in engineering, architecture and science.

The Purdue Triangle chapter house is located at 103 University Street, directly across the street from campus (map).
