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.
The imaginary line that divides the Earth into two halves is called the Equator.

That line is called diameter. It divides a circle into two semi circles.
The line that divides the Earth into two equal halves is called the equator. It is an imaginary line that runs horizontally around the Earth at 0 degrees latitude.
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.
Every line bisector divides a line into two halves: by definition!
line of semtry
A dividing line between two places is usually called a border.
