they lie in the same plane
Skew lines cannot lie in the same plane.
Two lines can lie in one plane. For example, parallel lines are lines that intersect and lie in the same plane.
Parallel
No. You can only define a circle by radius, diameter, area, perimeter. Concentric circles have the same centre, therefore, if they were the same circles with the same radius, then they would all lie on top of each other and be effectively one circle.

they lie in the same plane
Skew lines cannot lie in the same plane.
Points that lie on the same plane are coplanar. Generally, three points have to be coplanar, but more than that can be in any plane.
A great circle is a circle on the surface of a sphere that has the same center as the sphere, while a small circle does not share the same center as the sphere. Great circles have the largest circumference of all circles on a sphere, whereas small circles have smaller circumferences. The equator is an example of a great circle on Earth, while lines of latitude other than the equator are examples of small circles.
non-coplanar points are points that does not lie on the same plane... by:GRAETIA VILLANUEVA...
coplanar (which means that they lie on the same plane)
Points or lines that lie on the same plane are coplanar.
Coplanar points lie on the same plane. A plane is a flat, two-dimensional surface that extends infinitely in all directions. Coplanar points can be thought of as points that all lie in the same plane and can be connected by straight lines without leaving that plane.
They are lines or points that lie on the same plane. Remember 3 or more points are collinear if they lie on the same line. IF those lines lie on the same plane they are coplanar.
Two lines can lie in one plane. For example, parallel lines are lines that intersect and lie in the same plane.
