It could be an arc (a curved portion of the circumference), a chord (the straight line distance between two points) , or a wedge (the plane area bounded by two radii and an arc).
Remember the circle is a plane figure, not the curved line we draw. " A circle is bounded ... ."
A chord is a line which connects two points which lie on a circle.
a chord
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.
