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.

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 straight line that goes through the middle of a circle?
The diameter
Is a diameter a line segment that passes through the center of a circle?
Yes, a diameter is a line that goes between two points on the circumference of a circle and passes through the center point.
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 the line that goes across a circle?
The line that goes around, or envelopes, a circle is the circumference of the circle. It is found by multiplying the diameter of the circle, which is a line that crosses the center, by pi.
