Discover Triangle At Iowa State University

Founded in 1907 at the University of Illinois, Triangle is a social,  professional STEM organization of Engineers, Architects,  and Scientists.  We are the only national social fraternity requiring specific fields of study, and Triangle is one of only three national fraternities that does not have a Greek letter name.  The Iowa State Chapter was founded in 1964 and had a strong tradition of recruiting academically focused men. In addition, we strive to find men that live their life with integrity - those who make the choices to be leaders,  scholars, professionals, and gentlemen in all aspects of our lives.​ 

Triangle has much to offer academically and socially. We understand the balance between these areas and strive to attain excellence while maintaining a friendly and inviting home where lifelong friendships can be made.   Triangle brothers strive to be leaders in the campus,  local community, and their chosen fields of studies. Triangle offers opportunities to get involved and gain leadership experience. By joining Triangle, you are also gaining access to a network of over 22,000 members and alumni that will be there to help you out throughout your life's journey.
