It is a closed plane figure bounded by four straight line segments.
Any piece of a line has an infinite number of points on it, whether it's straight or curved. A line segment is a section of a line bounded by two endpoints. A line is continuous, but a line segment, is a segment of a line.
Assuming its endpoints are not equal, a closed interval of the real number line a has an infinite number of real numbers in it. Closed intervals of other ordered sets can have either a finite or an infinite number of elements. I am not sure I answered your question because I am not exactly sure what you are asking. Could you be more specific? Are you talking about a closed interval of the real number line or closed interval of some other ordered set? By finite do you mean 'containing a finite number of elements' or do you mean 'bounded by a finite number'.
a line segment is a part of a line that is bounded by 2 end points, and contains every point on the line between its end points
A line segment is a part of a line that is bounded by two end points, and contains every point on the line between its end points.
It is a closed plane figure bounded by four straight line segments.
A plane figure cannot be bounded by only one straight line. If the shape is bounded by lines which are not straight or by several straight lines the answer will depend on exactly what these are.

No, a line is not a polygon. A polygon is a closed plane area bounded by straight sides. A line, by itself, does not contain an area.

A signal is bounded if there is a finite value such that the signal magnitude never exceeds , that is for discrete-time signals, or for continuous-time signal (Source:Wikipedia)
No.... False... APEX:)!
