The diameter of a circle divides it into two halves
A line of symmetry divides a figure into two matching halves.
Hemispheres
What is axis of symmetry? the axis of symmetry is a line that divides a planar figure into two congurent reflected 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.
daimeter..
diameter
That line is called a "Diameter".
great circle
The Equator divides the Earth into two equal halves, the Northern Hemisphere and the Southern Hemisphere.
The imaginary circle around the earth that divides it into two halves is called the Equator. It is located at 0 degrees latitude and serves as the starting point for measuring latitude.
It is called a great circle. The equator is an example.
An equator is a circle that divides the surface of an object into two equal halves. The term is usually used to explain the circle that divides a plane,t like the Earth, in to two hemispheres.

A chord of a circle that contains the center of the circle is called a diameter. The diameter is the longest chord in the circle and divides it into two equal halves. It passes through the center, connecting two points on the circumference.
The 2 halves in a circle are the 2 semi circles.
A segment across a circle that passes through the center is known as a diameter. It divides the circle into two equal halves, creating two semicircles. The diameter is the longest chord of the circle and is defined as twice the radius.
