The line that divides a square into two equal parts is called the diagonal. The diagonal of a square is a line segment that connects two opposite vertices of the square. It is also the longest possible line segment that can be drawn within the square, dividing it into two congruent right triangles.

A chord is a straight line within a circle that divides the circle into two parts - these parts are called arcs.The diameter is a chord that runs through the centre of the circle and divides the circle into two equal parts.
The midpoint divides a line segment into congruent parts.
A chord.
A bisector - or diagonal
The imaginary line that divides the Earth into two halves is called the Equator.
That line is called a "Diameter".
A line which divides a shape in two is called a bisector.
It is a line of symmetry.
diameter
That line is called diameter. It divides a circle into two semi circles.
I am pretty sure in math, it is called a diameter
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!
