How many perpendicular bisectors can be constructed for a line?
There is only one perpendicular bisector for any given line.
Perpendicular lines intersect to form right angles.
A Bisector of a Line divides the line into two equal parts.
There can be many lines drawn perpendicular to a line.
There can be many lines drawn that bisect the line.
But only one line that is both perpendicular and a bisector.
