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 sixteen 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. They developed their plans quickly, and on
April 15, 1907, incorporated Triangle in the State of Illinois. The date of
incorporation has been designated as Founders' Day, and Triangle appropriately
celebrates it every year at each chapter.
