Triangle is a social fraternity, limiting its recruitment of members to male students majoring in engineering, architecture, and the physical, mathematical, biological, and computer sciences. It is the only member of the North-American Interfraternity Conference to limit its membership recruitment to these majors.

North-American Interfraternity Conference organization

The North-American Interfraternity Conference is an association of collegiate men's fraternities that was formally organized in 1910, although it began on November 27, 1909. The power of the organization rests in a House of Delegates in which each member fraternity is represented by a single delegate. However, the group's executive and administrative powers are vested in an elected board of directors consisting of nine volunteers from various NIC fraternities. Headquartered in Indianapolis, Indiana, the NIC also operates a small professional staff.


Triangle Fraternity organized at the University of Illinois at Urbana–Champaign in the fall of 1906 and was incorporated by the state of Illinois on 15 April 1907, which is celebrated each year as Founders' Day.

Illinois State of the United States of America

Illinois is a state in the Midwestern and Great Lakes region of the United States. It has the fifth largest gross domestic product (GDP), the sixth largest population, and the 25th largest land area of all U.S. states. Illinois is often noted as a microcosm of the entire United States. With Chicago in northeastern Illinois, small industrial cities and immense agricultural productivity in the north and center of the state, and natural resources such as coal, timber, and petroleum in the south, Illinois has a diverse economic base, and is a major transportation hub. Chicagoland, Chicago's metropolitan area, encompasses over 65% of the state's population. The Port of Chicago connects the state to international ports via two main routes: from the Great Lakes, via the Saint Lawrence Seaway, to the Atlantic Ocean and from the Great Lakes to the Mississippi River, via the Illinois Waterway to the Illinois River. The Mississippi River, the Ohio River, and the Wabash River form parts of the boundaries of Illinois. For decades, Chicago's O'Hare International Airport has been ranked as one of the world's busiest airports. Illinois has long had a reputation as a bellwether both in social and cultural terms and, through the 1980s, in politics.

Civil engineering engineering discipline and economic branch specialising in design, construction and maintenance of the built environment

Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewerage systems, pipelines, structural components of buildings, and railways. Civil engineering is traditionally broken into a number of sub-disciplines. It is considered the second-oldest engineering discipline after military engineering, and it is defined to distinguish non-military engineering from military engineering. Civil engineering takes place in the public sector from municipal through to national governments, and in the private sector from individual homeowners through to international companies.

Triangle's mission statement 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."


Code of Ethics

Triangle Fraternity was founded on high ethical and moral ideals, and expects the men of the fraternity to follow a set Code of Ethics, which is as follows:

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

  1. Observe the precepts of the Fraternity as set forth in the Ritual;
  2. Accept cheerfully my full share of any task, however menial, involved in maintaining a chapter home;
  3. Preserve and promote the chosen ideals of my Fraternity;
  4. Pay all personal bills promptly, and always live within my means;
  5. Help create in my chapter home an environment in which enduring friendships may be formed;
  6. Maintain a creditable scholastic record;
  7. Promote the welfare of my profession;
  8. Maintain my self-respect by proper conduct at all times;

  10. Pay the price of success in honest effort.

A colony is a probationary body of a national fraternity or sorority. It can be considered a new Greek organization that is awaiting official recognition from their international headquarters to maintain a chapter on their college’s campus. A group wishing to become a member of a fraternity or sorority must first petition for status as a colony. The entire membership of the colony remains as uninitiated associates, usually learning and operating under the guidance of an advisor from the national organization and/or from a sponsoring chapter. If the colony prospers and meets its goals as set out by the national organization, the colony may later be chartered and the membership initiated. After this the sorority or fraternity will become a full chapter of the fraternity. This practice varies with different sororities and fraternities; however, many of them follow procedures and practices very similar to one another. Everything depends on the official nationals of each individual organization.
