Question 338955: Given a segment, how many lines are there in a space that are perpendicular bisectors of the given segment? (make a sketch) Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! If it's in 2-space (the x-y plane) there's 1.
If it's in 3-space there's an infinite number. There'a a plane normal to the line thru the point.
