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!
