The correct term for a line segment with both endpoints on a circle is a chord. The diameter of a circle is also a chord.
"Curved" refers to something that deviates from a straight line. It may refer to a bend in the road, a line on a graph, or the trajectory of a baseball.

A point is an undefined term. But given two points, they can be joined using a line segment.
line segment
A line segment is a line that has boundaries. It's a straight line that links two points and does not extend beyond them. A line segment is most commonly used in Geometry. The term 'segment' means a portion of, or a part of. A line segment can be any portion of an existing line, and can be either a piece at one end of the line, or a piece within the length of the line. A circle segment can be either a pie shaped portion of the entire area of the circle, or a portion of the perimeter (circumference) of the circle . The latter should be expressed as a circumferential portion, to avoid confusion.
