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 geometrical curve is defined as any set of points. Therefore, counter-intuitively, a straight line is also a geometrical curve.
It's a "LINE" or a "CURVE"
Yes, but not a straight line.
a polygon is a shape with 5 corners A pentagon has five sides. A polygon has 3 or more sides, is closed and has line segments as the sides ( no curved sides ).
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.
A straight line, a triangle, an octagon, a pentagon, a hexagon a square a rectangle a.........

A curve.
A straight line that intersects a circle or curve at two points, but which has both end points outside the circle or curve is called a secant. A straight line that links two points on a circle or curve is called a chord. A straight line which touches a circle or curve at one point is called a tangent. A straight line that cuts a circle or curve at one point is a straight line.* For moving diagrams see Related links below this box.
A tangent at that point where a straight line just touches a curve and a secant line when the straight line bisects the curve.
In geometry a straight line that touches a curve is called a tangent.
A curved line is a line that is not straight.

A polygon
It is a straight line that touches the curve such that the line is perpendicular to the radius of the curve at the point of contact.
Any shape at all - other than a straight line. It could be a smooth curve, or a zigzag or a set of disconnected bits - whatever.
