A social, professional and STEM Fraternity at Iowa State University
Triangle is a social Greek Fraternity, founded in 1907, whose membership is major-specific for those men that are pursuing a degree in Engineering, Architecture, or Science fields. Our men play leading roles on campus, in our community, and have an impact on others that remain their entire lives. Through our Philanthropic work, Intramural Sports participation, academics, campus/community involvement, and member development, we strive to be outstanding.

BROTHER SPOTLIGHT🔺 Meet sophomore, Owen Mattson, studying Mechanical Engineering from Lakeville, MN! Owen had a busy first year being a main character in Yell Like Hell and Lip Sync, winning Mr. APhi Foundation, and making the Dean’s List for Fall and Spring! Read more about why Owen chose Triangle ⤵️
“Triangle has been the best decision I’ve made because of the true friendships I’ve found. It really does feel like a brotherhood and everything I’ve done in Greek Week and Homecoming has added a lot to my Iowa State experience. Everyone around me is a good influence to excel academically, but the fraternity has also opened up my social life to so many great experiences.”
We’re grateful to call Owen our Brother!
