WILL MARK AS BRAINLIEST: No one answered my previous question so I am reposting:
"If two points lie in a plane, then the line joining them lies in that plane."
For that postulate in Geometry, there is something I don't get. A plane is a shape with edges that go on forever, right? So it means if there is a plane, then covers the entire flat surface. So even if on the picture, the points are on the "outside" of the shape representing the plane, it still means they are in the plane right? Sorry if this is confusing to some people, I tried to make it as simple as possible but I guess I kind of failed, haha.

Anyways I would appreciate any answer explaining this and why. Thank you!

Step-by-step explanation:

since postulate in Geometry is assumed to be true but not proof, i guess the picture can show you that what meant is a line segment which connect two point on the line

Explanation:

Yes, planes and lines go on forever. Any diagram of such must necessarily be limited, and cannot show all of the points on the plane or line.

However, a diagram that shows planes and lines is necessarily drawn in two dimensions (on a flat screen, sheet of paper, or other media). Points may be drawn on the diagram that are intended to be understood as being on the plane or line, and other points may be drawn that are intended to be understood as being not on the plane or line.

So, if a plane is drawn as a rectangle or parallelogram, points that are intended to be understood as not on the plane are generally shown outside the boundaries of that parallelogram. They may be above or below the plane, depending on how/where they're drawn and what other clues the diagram offers.
