Next, applying cofactor expansion along the third column, we obtain: = is real are collinear. WebPoints on a line. In any geometry, the set of points on a line are said to be collinear.In Euclidean geometry this relation is intuitively visualized by points lying in a row on a "straight line". However, in most geometries (including Euclidean) a line is typically a primitive (undefined) object type, so such visualizations will not necessarily be appropriate.
