LOGO Instructions

Below are instructions to make six different pictures using LOGO. When you have entered them onto the computer, look at the picture, and draw this in the box provided.

1	2	3	4	5	6
fd 50 rt 90 fd 50 rt 90 fd 50 rt 90 fd 50 rt 90	rt 90 fd 50 lt 90 fd 50 lt 90 fd 50 rt 90 fd 50 rt 90 fd 50	fd 10 rt 90 fd 20 rt 90 fd 30 rt 90 fd 40 rt 90 fd 50 rt 90 fd 60 rt 90 fd 70 rt 90 fd 80 rt 90 fd 90 rt 90 fd 100	fd 30 rt 90 fd 50 rt 90 fd 30 rt 90 fd 50 rt 90	fd 20 rt 45 fd 20 rt 45 fd 20 rt 45 fd 20 rt 45 fd 20 rt 45 fd 20 rt 45 fd 20 rt 45 fd 20 rt 45	fd 60 rt 90 fd 40 bk 40 lt 45 fd 40 bk 40 lt 45 fd 40 bk 40 lt 45 fd 40 bk 40 lt 45 fd 40 bk 40

LOGO also understands another instruction called REPEAT. This repeats your instructions a number of times (saving you from lots of typing!). All you have to do is type the following...

So, if you want the computer to repeat the instructions "fd 6 rt 90" four times, type in "repeat 4 [ fd 6 rt 90 ]".
Experiment with this new command, and try to work out how you can make pictures 1, 4 and 5 using it.
