no they form a line segment
Line segments that form a polygon are called its sides.
Typically line segments are used to form shapes such as triangles or squares, etc.
If the vertex is at the centre of the circle then this forms a sector of the circle.If the two endpoints and the vertex form an angle in a segment, then the vertex can be at any point on the circle within the same segment and all angles so formed are equal.
Normally a straight line segment.
If you mean "what is the radius of a circle", then the answer is the line segment or length from the center of circle to the set of points that form the circle. The radius is also half of the diameter.

If available, a protractor or a right drawing triangle can be used. If restricted to ruler and compass, a right angle can also be constructed to a given line segment by drawing a circle, with a radius less than the length of the line segment but more than half that length, with each end of the line segment as a center and connecting the two points of intersection of the two circles above and below the line. The line connecting to two intersections of these circles will form as right angle to the line segment.
a right angle
Let us assume you have a circle drawn with the center identified. Then draw one straight line through the center. Measure the length of the line bound by the intercepts of the straight line with the circumference of the circle. The line segment is the diameter. Another case would be that you have a circle drawn with no center marked. Draw one straight line through the circle. Use a compass to draw the perpendicular bisector of the line segment bound by the intercepts of the straight line with the circumference of the circle toward the inner circle (the center of a circle cannot lie outside the circle!). Repeat drawing another (different) straight line through the circle and finish with a perpendicular bisector. The two bisectors will intercept at the center of the circle. Then you can proceed the same way as described in the first paragraph above. Hint to draw a perpendicular bisector of a line segment: take one end of the compass, pivot the point at one end of the line segment and mark an arc with the other end on both sides of the line. Move the compass and pivot one point at the other end of the line segment. Mark an arc with the other end on both sides of the line. If the procedure is done correctly, the two arcs, one from each end, should intercept on one side of the line. There is another intercept of the two arcs on the side of the line. Connect the two arc-intercepts with a straight line. Convince yourself that the line bisects the straight line at a right angle. This last line is the perpendicular bisector of the original line (The first and last lines form the perpendicular bisector of one another). ===================
Line segments are parts of a line that have fixed endpoints. In Geometry, line segment form the edges of the polygon and appear in countless ways. This can only measure the length of segment but not of a line.

no. A segment is a line with end points. Rays start in one place and go on forever.
Normally a straight line segment.
Yes as for example the diagonals of a square
