Hello, and welcome to the homepage for the Oklahoma Chapter of Triangle Fraternity.
Triangle is the national men’s social fraternity of engineers, architects and scientists. There is no other organization like Triangle Fraternity. While there are plenty of social fraternities out there, Triangle’s focus on these specific areas of academics makes us unique in the fraternal world.
Triangle began in 1907 at the University of Illinois with a group of Civil Engineering students who wanted to live together. Since then it has grown to more than 35 chapters at universities across the United States. Triangle first appeared on the OU campus in 1976 and was formally installed as the Oklahoma Chapter in 1979.
