Best Answer

A cord that crosses the center of a circle is a diameter, which divides the circle into two equal halves. It is a line segment, and it is the longest cord that can be drawn within a circle.

However, if the segment begins at the center rather than crosses through it, and has the other endpoint on the circumference of the circle, it is not a cord, but is a radius of that circle.

A cord that passes through the center of a circle is a diameter of that circle. And you've probably guessed that this is the largest cord of that circle.

The point from which the circle is drawn IS the center.

Yes, a cord that is a diameter always passes through the center of a circle. And it's also the longest cord of that circle.

A diameter of a circle must pass through the center of that circle. A cord is a line segment that has its endpoints on the circumference of a circle. It can be any line segment. If that cord also passes through the center of the circle, it is said to be a diameter of that circle. A diameter of a circle is the longest cord of the circle.

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.

A cord of a circle is any line segment connecting any two unique points on the curve. Any cord drawn through the center of the circle will be a diameter of the circle. These cords will be the longest cords that can be drawn, and any one of them can bisect the circle into two identical parts.

A diameter of a circle must pass through the center of that circle. A cord is a line segment that has its endpoints on the circumference of a circle. It can be any line segment. If that cord also passes through the center of the circle, it is said to be a diameter of that circle. A diameter of a circle is the longest cord of the circle.

Yes, the perpendicular bisector of a cord is the shortest distance from the centre of a circle to the cord.

If that cord of the circle passes through the center of the circle, then the cord is a diameter of that circle.

Draw a cord through the circle (a line through the circle, but not too close to where you imagine the center to be). With construction techniques, find the perpendicular at the center point of the cord, and draw the perpendicular. Do the same thing again starting with a different cord, and the two perpendiculars will intersect at the center of the circle.

A chord that passes through the center of a circle is its diameter.

The cord of a circle that contains the center of that circle is a diameter of that circle.

If you draw a line from the center of a circle to the edge of a circle, you have drawn the radius of the circle. If you draw a line from the edge of a circle through the center of the circle and on to the edge on the opposite side, you have drawn the diameter of a circle. The radius of a circle is one half the diameter of a circle.
