Uses triangle area determinant to check if 3 points are collinear. If they are, they can't make a triangle, so the determinant will be 0!
0 1 2

Fun fact, you can use this same determinant to check the order of the points in the triangle
NOTE: Should this use a buffer instead? NOTE: Should this use a buffer instead? [x0, y0, x1, y1, x2, y2]?
