It is the diameter of the circle
A secant is a line that passes through a point on the circle and the center of the circle. It intersects the circle at two different points.
Yes, a diameter is a line that goes between two points on the circumference of a circle and passes through the center point.
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 chord is any line segment that connect two points of a circle. If a chord passes through the center of the circle it is called the DIAMETER of the circle. The diameter of any circle is the longest chord of that circle as well.
A diameter - provided it meets the boundary of the circle or sphere on opposite sides.
The diameter. Feel free to facepalm.
A line segment with its endpoints on the circumference (curve) of a circle is called a chord of that circle. If it passes through the center of the circle (which it can, but does not have to do), it is called a diameter of the circle. See the links below for more information.Is called a radius.
