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 straight line from the center of a circle to the outer edge is called a radius.
A straight line across a circle through the centre?
Line through the center of a circle is the diameter or distance across the circle.
Do all chords of a circle pass through the center of a circle?
No, not all chords of a circle pass though the center of that circle. Any cord that does pass through the center of the circle is called diameter of that circle.
Straight line from the center of a circle to the outside diameter is called?
A line segment with the center of a circle as one endpoint and the other endpoint on the circumference of the circle is a rdius of that circle.
