Illustrate, if possible, each one of the following with a rough diagram:

(a) A closed curve that is not a polygon.


(b) An open curve made up entirely of line segments.


(c) A polygon with two sides.


(a) A closed curve that is not a polygon – a polygon is a two-dimentional figure which has minimum 3 or more straight lines. So, circle isn’t a polygon.
