yes
If they lie in the same plane.
Four non-collinear points can form exactly one plane. This is because a plane is defined by three non-collinear points, and adding a fourth point that is not in the same line as the other three does not create a new plane; rather, it remains within the same plane defined by the initial three points. Therefore, all four points lie in the same unique plane.
all of them are collinear they lie in the same plane
lie on the same plane and are collinear
-lie in the same plane -are collinear
Sometimes.
coplaner points- are points lying on his the same plane,.. solution: plane R contains XY XY contains X and Y...
There are no planes containing any number of given points. Two points not the same define a line. Three points not in a line define a plane. For four or more points to lie in the same plane, three can be arbitrary but not on the same line, but the fourth (and so on) points must lie in that same plane.
I dont think that "If four points are collinear they are also coplaner," is the same thing as "If four points are coplaner they are also collinear,". The definition of collinear is at least three points on the same line. To define a plane is to have threenoncollinear points.
Yes, when they are the coordinates of a straight line equation.
Points or lines that lie on the same plane are coplanar.
Yes, since any line can be contained in a plane.
