__Polygons__

**A polygon is a closed figure formed of three or more line segments.**

**Examples of polygons are triangle, quadrilateral, pentagon and
hexagon.**

**Example: Classify the following curves as i) Open ii) Closed**

**Example: Consider the given figure and answer the questions:
a) Is it a curve?
b) Is it closed?**

**a) Yes, it is a curve because a curve is drawn without lifting the
pencil from the paper and without using a ruler.
b) Yes, it is closed because the curve forms a closed path.**

**Example: Draw any polygon and shade its interior.**

**A polygon is a closed figure formed of three or more line segments.**

**Example: 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.**

** **

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

**c) A polygon with two sides cannot be drawn as minimum three
line segments are required to make a polygon.**
