Founded in 1906 at the University of Illinois, Triangle is a fraternity of engineers, architects and scientists that has initiated over 28,000 men throughout the United States. Triangle alumni have gone on to become astronauts, co-found massive video game companies (Blizzard), and even win an Olympic gold medal. Since it's incorporation on April 15th 1907 (Founders Day) the fraternity has provided

leadership experience and brotherhood to men in 25 states, while also establishing the values of honor, friendship, character, and courage in all its members through its code of ethics. Since it's establishment in 2011 the UCSD chapter has sought to live up to these values by creating an environment where enduring friendships may be formed, and teaching all it's members to pay the price of success in honest effort. While Triangle is a fraternity of STEM majors, it's members have been active in all parts of campus ranging from student organizations to student government. On-campus triangles have served as principal members of student organizations, directors of campus musical groups, and elected representatives In Associated Students. Local Alumni have gone on to work at places such as Amazon, Qualcomm, the US Air Force, and the US Navy, and our chapter is actively engaged with our Alumni base. Interested in rushing Triangle?
