Polygon
Click the Home | Insert | Polygon command, the 
button, or the Features | Insert | Polygon command to draw an irregularly shaped area. Polygons must have at least three vertices (points). Polygons can be converted to 3D polygons with the addition of Z coordinates to vertices.
To draw a polygon:
- Click the Home | Insert | Polygon command to begin drawing a polygon.
- The cursor changes to a cross hair cursor to indicate drawing mode.
- Move the cursor over the location for the start of the polygon and click the left mouse button.
- Move the cursor to the next position along the line and click again.
- Continue this procedure until you click the final point. Then press the ENTER key.
The first and last points are automatically connected and the new polygon is drawn. To end draw polygon mode, click on another toolbar button or press the ESC key on your keyboard.
