Many of the concepts and ideas shared below are synonymous across all chapters of Triangle. Read on and contact us to learn more about our specific chapter at Michigan Tech.

About Us

Triangle is the fraternity of engineers, architects, and scientists. It is the only nationally recognized social fraternity to define its membership in such a way. Triangle is one of three member fraternities in the National Interfraternity Conference to not have Greek letters (it is truly “Triangle”).

Triangle Fraternity has published a Purpose Statement, which reads:

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.

All Triangle chapters aim to uphold this purpose, and do so by careful selection and development of members.


In addition to the Purpose Statement, Triangle men pledge to uphold the Code of Ethics; this is a moral code by which every Triangle man is expected to live, and by which he shall judge the character of his actions. The Code of Ethics is as follows:


As a member of Triangle, I recognize my obligation to:

– Observe the precepts of the Fraternity as set forth in the Ritual;

– Accept cheerfully my full share of any task, however menial, involved in maintaining a chapter home;

– Preserve and promote the chosen ideals of my Fraternity;

– Pay all personal bills promptly, and always live within my means;

– Help create in my chapter home an environment in which enduring friendships may be formed;

– Maintain a creditable scholastic record;

– Promote the welfare of my profession;

– Maintain my self-respect by proper conduct at all times;

– Uphold faithfully the traditions and program of my Alma Mater;

– Pay the price of success in honest effort.


Triangle Fraternity was founded in 1907 at the University of Illinois Urbana-Champaign.

Organized by 16 junior civil engineering students in 1906, and formally chartered by the University on April 15, 1907 (which Triangle men recognize as Founders Day), Triangle started as a fraternity for civil engineers. Its initial expansion in the early 1900s included Purdue University, the Ohio State University, and the University of Wisconsin – Madison.

Below are some dates of note.


January 1921: a referendum was passed to allow men in any branch of engineering to join the Fraternity, not just civil engineers.

August 1961: National Convention held in Milwaukee, WI voted to allow students of chemistry, physics, and mathematics to join the Fraternity.

January 1983: Computer Science is designated as an allowed major in the Fraternity.

April 1988: The Michigan Tech chapter of Triangle is chartered on the campus of Michigan Technological University.

2006: The Michigan Tech chapter is suspended due to low membership.

April 2012: The Michigan Tech chapter is re-chartered on the Michigan Technological University campus
