### Grade 3 - Mathematics8.3 Polygons

 Polygons are closed figures that are formed by line segments. Each side is a line segment. The point where two line segments meet is a vertex. The sides do not cross each other and exactly two sides meet at every vertex. The segments that form the boundary are sides, which meet at a vertices to form the interior angle. If we connect two vertices that are not adjacent on the polygon, we form a diagonal. Examples: Squares, Triangles, Rectangles, etc. Directions: Answer the following questions. Also draw 10 examples of polygons an name the sides, vertices and diagonals on a sheet of paper.
