YWhy would people in a totally different culture with little or no contact (until relatively recently) with the rest of the world develop the exact same set of "premises"? Are you gonna tell me it's because we all share the same gravitational constant or some bullshit like that?
I don't know. I guess because it began from simple counting systems based on every day life.

You can't show me any alternative "premise" which makes triangles add up to 190 degrees under those conditions. Unless you want to play semantic games and talk about 4-sided triangles or something.
that's what I was trying to say. any mathematical 'truth' is true only under certain conditions.
euclidian geometry has five premises (or postulates, as they are usually called). if you are working in euclidian space you are assuming those five postulates to be true. they are your premises. non euclidian geometries share the first four postulates with euclidian geometry, but each have a different fifth postulate. that triangles' angles always add up to 180 only holds true under the euclidian postulates. once you change the postulates, a triangle's properties start to change also.
to ask me to "show me any alternative 'premise' which makes triangles add up to 190 degrees under those conditions" doesn't make terribly much sense. to change the premises means we changed the conditions.

U.S. Population Reaches 314,159,265, Or Pi Times 100 Million: Census

The U.S. population has reached a nerdy and delightful milestone.
Shortly after 2:29 p.m. on Tuesday, August 14, 2012, the U.S. population was exactly 314,159,265, or pi (π) times 100 million, the U.S. Census Bureau reports. The U.S. Census Bureau's Population Clock projects the real-time size of the U.S. population based on monthly population estimates.
Pi (π) is a unique number in multiple ways. For one, it is the ratio of a circle's circumference to its diameter. It is also an irrational number, meaning it goes on forever without ever repeating itself. Are you remembering how much you loved geometry class? You can check out pi to one million places here.
