A line extends indefinitely on both sides. A part of the line that lies between two distinct points on a line is called a line segment.
A line segment whose endpoints lie on a circle is called a chord of the circle.
Remember that a chord of a circle that passes through the center of a circle is called a diameter of the circle.

A circle is a closed curve. A line segment whose endpoints are on the edges of the circle is referred to as a chord, or if it passes through the center point, as the circle's diameter.

If a line segment AB subtends an angle t deg at the centre of the circle of radius r, then:
The length of the minor arc is:
2 pi r t/360
= pi r t / 180
and
the length of the line segment is:
2r sin(t/2).

A line segment connects two points. The arc, radius, circumference, etc. of a circle are line segments.
