A line of symmetry divides a figure into two matching halves.
What is axis of symmetry? the axis of symmetry is a line that divides a planar figure into two congurent reflected halves
The sagittal plane, also known as the vertical plane, is the imaginary line that separates anterior from posterior. This plane is referenced when dealing with any anatomical diagram.

a symmetrical line.
To bisect is to cut or divide into halves. A bisecting line would then be a line that divides another line in half or a line that divides an angle in half.
A perpendicular bisector [for a given line segment] is a line that meets it at 90 degrees and divides it into two halves.
A bisector is a line that divides another into two halves. If the second line is at right angles to the first, it is perperdicular. So, a perpendicular bisector of a side is a line which is at right angles to the side and which divides the side into two halves.
a bisecting line is a line that divides something into halves.
Every line bisector divides a line into two halves: by definition!
A perpendicular bisector is a line that divides a given line segment into halves, and is perpendicular to the line segment. An angle bisector is a line that bisects a given angle.

Bisector means a line that divides another lines in two equal halves.
That line is called a "Diameter".
