True.
Yes, two points are always collinear. You can draw a line through any two points.
YES!
False. Three collinear points determine a line while three non-collinear points determine a plane ( A Triangle)
They must be coplanar before they can be colinear. They lie on the same line or equivalently, they must all satisfy te same linear equation.
True.
true
true
true
Yes, since any line can be contained in a plane.
Is false
They are on the same plane.
Not enough information. Collinear means the points are on the same line. If you have any three points, they may, or may not, be on the same line.
Yes, two points are always collinear. You can draw a line through any two points.
YES!
No. If the four points are coplanar, they determine only one plane!
If three points all lie on the same line, then the points are said to be "collinear". This is also true if the slope from each point to the next is the same.
