41. In all of these configurations, each point has three other points that are not collinear with it. 42. :: So it won't matter if the axes of rotation are not collinear at all. 43. These three attributes : origin, marque and performance are said to be collinear or non-orthogonal. 44. The Cauchy & ndash; Schwarz inequality is met with equality when the two vectors involved are collinear . 45. Centuries before, Pappus of Alexandria had solved a special case : when the three points are collinear . 46. If all five points are collinear , then the remaining line is free, which leaves 2 parameters free. 47. However, not all sets of four points, no three collinear , are linearly separable in two dimensions. 48. That is, the points of intersection of the pairs of opposite sides of the hexagon BEKHZG are collinear . 49. If the determinant of this matrix is 0, then the sequence is collinear -neither concave nor convex. 50. Therefore, there exist arbitrarily large finite sets of non-collinear points with integer distances from each other.
