If you can draw a line then Polyline will be a snap. Think of it as connecting the dots, or in this case the coordinates. In LINE you have two sets of parameters. The start and end. Polyline, expands on that. You can keep adding more coordinates. If you have never played around with Line, then I'll give a quick explanation of how the parameters work. Line has two sets of parameters. FIRST SET: This determines the location you want to begin drawing the line. Let's say 20,20. That means I want to start drawing my line at 20 from the left edge and 20 down from the top. SECOND SET: This determines where the line will end. Lets say at 200,270. This means, 200 from the left edge and 270 from the top. Now Polyline is the same, but different. You don't have to stop at two coordinates but keep going. Take for instance the image below: I used these coordinates. ( 0,0 100,150 150,100 250,100 398,398 220,290 and the result is..... As you can see, connect the dots.
.
Polygon is the same as Polyline except for one difference. Polygon will connect the ending coordinate to the beginning coordinate.
You can make some interesting shapes with this one.
