​​Who Are We?

​​Building Better Men

Founded in 1907 at the University of Illinois, Triangle is a social fraternity of Engineers, Architects and Scientists. We are the only national social fraternity that requires 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 has 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.
