What is the minimum number of points needed to identify a line?
Two. Two points determine a line. Three points determine a plane.
Three what points determine a plane?
Any three points will determine a plane, provided they are not collinear. If you pick any two points, you can draw a line to connect them. An infinite number of planes can be drawn that include the line. But if you pick a third point that does not lie on the line. There will be exactly one plane that will contain the line and that point you added last. Only oneplane can contain the line, which was determined by the first two points, and the last point.
When would three points not determine a plane?
A series of 3 points will always determine a plane unless 2 or all 3 points are identical points (they have the same coordinates).If the idea is to have the three points determine oneplane, a unique plane, then three points will do that as long as none of them have the same spacial coordinates (have identical locations) or as long as the three points do not lie on a single line.If a straight line can be drawn through all three points, they will not form one unique plane either.
What do you call two or more points that lie on the same plane?
Points on the same plane are coplanar lines.
Is a line joining two points not necessarily in the plane containing the two points?
If it is a straight line it must be in the same plane. Otherwise not necessarily.
