Even if it were a finite length line the answer would still be infinite. The more critical factor is that you can make infinite subdivisions of a line with a point at each subdivision.

ok if you make a line and put two points on it you have a segment not a line anymore so if you put 10 dots on it you will have 9 segments and nomore line

The person said points, not dots, though.

Man what a childish questions...

double yawn.

points not dots gosh

whats with the calculator?

On line segments-- Marking C on line segment AB gives NEW line segments AC and CB while AB remains. If you mark 10 points, you create 45 line segments.

I can't even see how the difficulty on this is 1.5. It should be more like 0.01. Sorry, but this question is infinitely easy.

LOL why is there a calculator here is this supposed to be trick question?? rofl this should be a joke lol

Umm... riiiiight...

1st one I got wrong tonight

P.S. don't forget to send me a message saying what subject you want me to make a quiz on!!!!

Yeah, stupidly simple.

I was going to make the observation that there are an infinite number of points on an infintesimally small line segment, but I see that my point has more or less already been made, although it's been made far fewer than an infinite number of times.

This is simply the statement of the first proposition of Euclidian Geometry although it all seems like Greek to some people!
