This blog will require you to do a little bit of research on the internet or in a book.

Question #1: I need for you to tell me "What is the definition of a polygon"

Definition: A closed figure that is composed of a FINITE numbre of line segments. It is derived from the greek words "poly" meaning many and "gonia" meaning angle.

Question #2: Is a Circle a polygon?

3 sided = Triangle
4 sided = (remember I did not say that all 4 sides are equal) Quadrilateral
