A line of symmetry divides a figure into two matching 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.
The diameter of a circle divides it into two halves
All bisectors intersect the line segment at the midpoint. There can be multiple bisectors, intersecting at the midpoint at different angles, but they all intersect the line segment at its midpoint. The midpoint separates the line segment into two equal halves.
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.

A symmetrical shape has equally matching parts when divided into halves. The dotted lines that divide the shapes into equal halves is called a line symmetry.
This is called the longitudinal fissure. The halves are not actually separate.

Any symmetrical figure has two halves that match. By definition, you cannot have more than two halves of a figure.

the center of the earth is called the halves of the earth

A mite has billateral symmetry because if you divide it lenghthwise, the two halves would be identical. But if divided any other way you would not have two matching halves, such as you would with a starfish or jellyfish, which have radial symmetry.
