If third argument is False, you will get a polylines joining all the points, not a closed shape.

**note**
cv2.polylines() can be used to draw multiple lines. Just create a list of all the lines you want
to draw and pass it to the function. All lines will be drawn individually. It is a much better and
faster way to draw a group of lines than calling cv2.line() for each line.

### Adding Text to Images:
To put texts in images, you need specify following things.
- Text data that you want to write
- Text data that you want to write
- Position coordinates of where you want put it (i.e. bottom-left corner where data starts).
- Font type (Check **cv2.putText()** docs for supported fonts)
- Font Scale (specifies the size of font)

### Result
So it is time to see the final result of our drawing. As you studied in previous articles, display
the image to see it.
