Does a secant line pass through the center of a circle?

No, a secant line does not pass through the center of a circle. A secant line is a line that intersects a circle in two distinct points. Only a line passing through the center of a circle is called a diameter.


What is the straight line through the center of a circle 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.


What is the name of a line drawn from one side of a circle to the other through the center?

This is called the diameter of the line that passes through the center of the circle. Half of that line is called the radius.


What is a line passing through the center of a circle with both end points on the circle called?

This is a line segment called a diameter of the circle.


What is a line through a circle that does not go through the center?

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.

What is a line that passes through the center of a circle?

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.

A line through the center of a circle from one side to another?

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.) The line may or may not pass through the center of the circle, but it is still called a secant line in any case. 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.

What is a line that goes through a circle from top to bottom?

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 chord of that circle. If the chord of a circle passes through the center of that circle, it is a diameter of that circle, which is the longest chord of the circle.
