bisect each other?

 

that's not true if they are both segments of the same line though.

That's probably right, thanks

Lines have infinite length

 

We should be talking about line segments 

 

Then the segments have equal length

 

To see this.......draw a circle of any radius  with center O and any two diameters in the circle

 

Call the diameters AB   and CD...and these are equal

 

But  AO = BO = CO = DO  = radii

 

So....the radii are equal....and since O is the center.......the diameters have the same midpoint

 

 

cool cool cool

no they don't indecision

 

take the segment of length 2x defined by points (-x,0) and (x,0) this has midpoint (0,0) for any x
