I am pretty sure in math, it is called a diameter
That line is called diameter. It divides a circle into two semi circles.
It is a line of symmetry
Every line bisector divides a line into two halves: by definition!
It's called a Midpoint.
It is a line which divides into two (or more) rays.
That line is called a "Diameter".
A line which divides a shape in two is called a bisector.

It is a line of symmetry
When a line divides another in two equal parts, it is called a bisector. If the bisector happens to cross the other line at right angles, it is called a perpendicular bisector.

line of semtry
A line of symmetry divides a figure into two matching halves.
A dividing line between two places is usually called a border.
A bisector - or diagonal
