We typically think of these objects as points or lines, or 2D shapes. Points , lines , or shapes are non-coplanar if they do not lie in the same plane. Collinear points lie on the same line. If points are collinear, they are also coplanar. However, coplanar points are not necessarily collinear.

Two lines. Points that lie on the same line are called collinear points. If there is no line on which all of the points lie, then they are noncollinear points. The line segments can be translated to vectors ab, bc and ac where the magnitude of the vectors are equal to the length of the respective line segments mentioned.
In geometry, a set of points in space are coplanar if there exists a geometric plane that contains them all. Points A, B and E are the set of points that are not coplanar.
Definition of noncollinear. We know that the group of points which lie on the same plane are coplanar points. Hence, points are coplanar. Collinear Vectors : They can have equal or unequal magnitudes and their directions may be same or opposite.
Two vectors are collinear if they have the same direction or are parallel or anti-parallel. Coplanar Vectors : A system of vectors is said to be coplanar , if their supports are parallel to the same plane. The plane has two dimensions: length and width. But since the plane is infinitely large, the length and width cannot be measured. Just as a line is defined by two points , a plane is defined by three points. Given three points that are not collinear, there is just one plane that contains all three.
In three-dimensional geometry, skew lines are two lines that do not intersect and are not parallel. Two lines that both lie in the same plane must either cross each other or be parallel, so skew lines can exist only in three or more dimensions.
Two lines are skew if and only if they are not coplanar. Perpendicular Lines. Coplanar lines that are not parallel must intersect or cross each other. Perpendicular lines create four right angles at their point of intersection. Are points D and E collinear or coplanar? Category: science space and astronomy. Points D , E , and F lie on the same line. So, they are collinear.
