>Then why agree you talking about [0, pi/2]?
This guarantees that the point B exists. If I said
AB = [ 0, infty ]

then someone would say, "You can't put infinity at B."

>Only line segments with finite lengths
This is completely retarded. Line segments don't even have length until you attach a chart and a metric. On the other hand, you can prove the existence of the midpoint without attaching either, as I have done in the post above.

>Also how does your diagram work when A and B are infinitely far apart and therefore no circles centered on A and B exist that can touch each other?
