Like those of most other fraternities, Triangle's beginnings came from the desire of some congenial college friends to extend their friendship, not only through college, but also for life. It was in the fall of 1906 that 16 civil engineering Juniors at the University of Illinois began the association that became Triangle Fraternity. These Founders based their organization on the principles of honor, friendship, character, brotherhood, courage, and ideals.

In 1909 the Illinois chapter brought a similar group from Purdue University into their fellowship and Triangle became a national fraternity. Despite limitation of membership to those whose studies are in technology and science, Triangle is a general social fraternity and a senior member of the National Interfraternity Conference.

Triangle seeks members by program of study (list). Such restrictions are not based upon race, religion, color, or national origin. Course of study restrictions ensure a relatively homogenous group. Thus the brothers can help each other and support the environment for study that such curricula demand.

Now in its ninth decade, Triangle is a strong bond of closely knit chapters throughout the United States (map). Leaders on the university and college campuses where it has chapters are proud to wear the Triangle badge, and a great many leaders in professional and industrial fields are equally proud of their fraternity heritage through membership in Triangle.

Triangle continually strives for success, whether it be academically, athletically, or socially. As leaders on campus and in the community, Triangle Brothers lead by example. Triangles are involved in campus organizations such as Gimlet, Skull and Crescent, as well as Grand Prix, Purdue Solar Racing, and Boiler Gold Rush Team Leaders.
