Depends on the context: London has a tube (Metro) line which is called the Circle Line.
This is a line segment called a diameter of the circle.
That line is called diameter. It divides a circle into two semi circles.
the line from the centre to the edge of a circle is called?
A line that goes through a circle is a secant line. (Remember that a line is infinitely long.) Anyline that passes through a circle is a secant line, whether it passes through the center of the circle or not. Compare this to a line segment with endpoints on the circumference of a circle. That segment is called a cord of that circle. If the cord of a circle passes through the center of that circle, it is a diameter of that circle, which is the longest cord of the circle.
A line from the center of a circle to any point on the circle is called a radius.

Anyline that passes through a circle is a secant line, whether it passes through the center of the circle or not. Compare this to a line segment with endpoints on the circumference of a circle. That segment is called a cord of that circle. If the cord of a circle passes through the center of that circle, it is a diameter of that circle, which is the longest cord of the circle.
A straight line from the center of a circle to the outer edge is called a radius.
yes half of that line is called the radius (used to calculate the area of a circle)
A. If the line segment touches two points on the circle it is called as: 1. secant; if the line extends outside the circle. 2. chord; if the line is present only within the circle. B. If the line segment touches one point on the circle AND the center of the circle AND is present only within the circle it is called as: radius.
Any line that passes through a circle and touches two points on its circumference is a secant line. (Recall that a line is infinitely long.) If the line passes through the center of the circle, it is still called a secant line. Compare this to a line segment that has its endpoints on the circumference of the circle. That line segment is called the cord of the circle. If that cord passes through the center of the circle, it is a diameter of the circle, which is the longest cord of that circle.
The radius of a circle is one half of the circle's diameter, any line going from the center of the circle to the circle itself. A line connecting other points on a circle (or on any curve) is called a chord.
Is calleda tangent line. Is called a tangent line
