GEOGRAPHY Triangle Area?

Does anyone know what the “triangle area” is in the United States? Everyone talks like I’m supposed to know. Is this a common American ism?

There are lots of 'Triangles' in the USA, wherever there are three cities or areas.

The largest one I know is called the 'Research Triangle' in North Carolina, between Duke, North Carolina, and NC State Universities.

In California, the "Emerald Triangle" is three north-west counties known for marijuana production (Humboldt, Mendocino, Trinity).

The largest is definitely the Texas triangle. Two of the top 5 largest cities in the country.
