A straight line joining points on a circle is called a "chord" of that circle. If the line happens to pass through the center of the circle, then it's a "diameter" of that circle. The question asked about "points" on a circle, so two points on the circumference of that circle are being considered. (No line can join more than two points of a circle.)
That's called a chord.

Median line.
This is called the diameter of the line that passes through the center of the circle. Half of that line is called the radius.
A straight line connecting two points on a circle is a "Chord". If the chord goes through the center of the circle, it is called, "Diameter".
A line segment joining two adjacent vertices of a polygon is called an edge or a side. A line segment joining two non-adjacent vertices is called a diagonal.

A radius of a circle is a line segment joining the center of the circle to a point on the circle. All such segments have the same length, and this length also called the radius of the circle.
That's called a chord.

The line joining the pole and the centre of curvature of a mirror is called the principal axis. This line is a key reference point for determining the focal length and characteristics of the mirror.
The logifisicalup line.
Median line.
The lines joining the two poles are longitudes.
They are isobars.
That particular segment is the radius of the circle, which is half of the diameter.The radiusThe line segment (distance) from the center of a circle to any point on the diameter of the circle is called the radius.radius which is half the diameter and the area of the circle is pi*radius squared.A chord of a circle is a line segment that has its endpoints on the circumference of the circle.If a line segment is drawn from the center of the circle to the circumference (or curve), it is called a radius.If a chord passes through the center of the circle, its length is the diameter (width) of the circle.Radius joins the center of the circle to any point on the circle and a chord cuts through the circle but does not pass through the center.length of a line segment joining center andany poit on a circleThis is the definition of the radius of the circle, which is equal to one-half the diameter of the circleThe radius of the circle, equal to one-half of its diameter, is any line that goes from the center of the circle to any point on the circle.The distance between the center and the edge of a circle is called the radius.The distance between the center and edge of a circle is called the radius.RadiusThe distance from the center of a circle to its outer edge is the Radius.A line drawn between the center of a circle and the edge of the circle is called the radius.Radius.Diameter is the entire distance across the circle, and radius is from the center to the edge (so 2r=D).Radius :dRadiusThe distance is known as the radius and is drawn in a straight line from the centre of the circle to the edge of the circle itself
