Centroid Question

[TerryRitchie]

Mid x, y for a rectangle would be exactly the same for the 2 right triagles that make it up, which would put the centroid right on the edge of the hypotenuse. So I think that proves the idea incorrect.

Yeah, I was thinking about that too. I'm basically creating a rectangle around the points and then taking the center point of that rectangle as the center point of the x,y point collective. It "sounds" corrects to me but I'm not sure, that's why I'm asking for input.

Some of the reading I've encountered states you need to use Centroid calculation, others state barycenter calculation, yet others seem to somehow get mass involved. All confusing.
