When you put an invisible line through the middle of an object and both sides match.
A line through a circle that does not go through the center of the circle is a secant line. A line through a circle that does go through the center is still a secant line, by the way. Compare this to a line segment that has its two endpoints on the circumference of the circle. That line segment is a cord of the circle. If that cord of the circle passes through the center of the circle, then the cord is a diameter of that circle.
It's kind of like an invisible line. For example, say you have a square and you want to know how much triangles it has. You automatically know in your head its two because you drew that same line as a diagonal of the square.
Circle with a line through it is square yards, a square with a line through it is square feet
There is no name for it except "A line perpendicular to a line segment and passing through its midpoint".

The invisible line around which the Earth rotates is called its axis. This axis passes through the North and South Poles and is tilted at an angle of approximately 23.5 degrees relative to the plane of Earth's orbit around the Sun.
