linking falling dots together by a straight line ?!

i'm working on a project that has dots falling from top to bottom.
the player is supposed to connect them together by dragging his finger from one dot to another..
i've been struggling to make it happen, i don't know how to logically program the actual link. everything else is more or less done.
please help!

What do you mean connect them together? Do you want to add a line between them or do you want them to combine into a bigger dot?

It will just be a box, the length will be the magnitude of dot 1 - dot 2, the rotation will be the vector to angle of dot 1 - dot 2 and the position will be: x = ((magnitude of dot 1 to dot 2) /2) * cos(vector to angle of dot 1 -to 2) and y = ((magnitude of dot 1 - dot 2) /2) * sin(vector to angle of dot 1 - 2).
Of course that all might be wrong !
I'll test it out a bit later, it should be something like that.
Actually dump the ((magnitude of dot 1 to dot 2) /2) * cos(vector to angle of dot 1 -to 2) stuff, you can locate the x and y centre between two objects with a more simple . . .
(( Dot 2 X minus Dot 1 X )/2) + Dot 1 X
(( Dot 2 Y minus Dot 1 Y )/2) + Dot 1 Y
Anyhow, I've made you a quick demo, three falling dots connected by lines - forming an ever-changing triangle:

yes i just want to link them. its very helpful, thanks. but my dots spawn above the visible scene area and the fall out of the scene, how do i constrain their attributes if there is always a different dot?
Then spawn them above the visible scene area.
I'm sorry i should explain this differently. there are always new dots spawning in a random place above the scene and falling down and eventually out of the scene, so its always a new dot and a new link connecting the new one with the old..
