The secant.
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.
The line segment described is known as a diameter. It connects two points on the circumference of a circle or the surface of a sphere and passes through the center point, effectively dividing the circle or sphere into two equal halves. The length of the diameter is twice the radius of the circle or sphere.
A line segment that has endpoints on a circle is called a chord. A chord connects two points on the circumference of the circle and divides the circle into two arcs. The longest chord in a circle is the diameter, which passes through the center of the circle.
The line segment that connects any two points on a circle is called a chord. If you connect three points on the circle, the segments connecting them form a triangle inscribed within the circle, known as a cyclic triangle. The longest chord of a circle is the diameter, which connects two points on the circle and passes through its center.
