Best Answer

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.

It is the diameter of the circle.

A straight line from the center of a circle to the outer edge is called a radius.

Line through the center of a circle is the diameter or distance across the 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.

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.

Yes. In geometry, a diameter of a Circleis any straight Line_segmentthat passes through the center of the circle and whose endpoints are on the circle.

A chord is a line that joins to points on the circumference of a circle. If it passes through the center of the circle it's called a diameter.

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.

If it connects the center of the circle to the edge, it is the radius. If it is a straight line that connects the edges of a circle through the center, it is the diameter.

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.

No, the cord of a circle does not have to go through the center of that circle. A chord that does go through the center of a circle is a special case and is called the diameter. A chord can connect any two points on a circle.

The distance through the center of a circle is called the diameter.
