In geometry, a set of points in space are coplanar if there exists a geometric plane that contains them all. For example, three points are always coplanar, and if the points are distinct and non-collinear, the plane they determine is unique. However, a set of four or more distinct points will, in general, not lie in a … See more In three-dimensional space, two linearly independent vectors with the same initial point determine a plane through that point. Their cross product is a normal vector to that plane, and any vector orthogonal to this cross product … See more • Collinearity • Plane of incidence See more • Weisstein, Eric W. "Coplanar". MathWorld. See more Since three or fewer points are always coplanar, the problem of determining when a set of points are coplanar is generally of interest only when … See more A skew polygon is a polygon whose vertices are not coplanar. Such a polygon must have at least four vertices; there are no skew triangles. A polyhedron that has positive volume has vertices that are not all coplanar.
