Yes, two points are always collinear. You can draw a line through any two points.
Always.
YES. The intersection of two planes always makes a line. A line is at least two points.
always
False ( apex )
A line segment is a set of points between the two main end points. A line segment is always connected and has no open spaces.
Any two points are always collinear, since you can draw a straight line passing through any two points.
they are noncolinear if there are more than 2 points, if not then any two points always lie on the same line
It will intersect two points always because its a straight line and extends beyond the two points.
No.
"Collinear" means "on the same straight line".Two points are always collinear, because you can always draw a straight linebetween any two points. Three points may or may not be collinear.
Two points can always be connected by one, and only one, straight line segment.In other words, two points always define a line.And since they defined it, they're both on it.
