First Forward Into Logo



Now that you have seen how easy it is to draw squares triangles, pentagons, hexagon, heptagons etc. let us use these shapes as basic units of a pattern.

Why not repeat what you have already repeated!

Drawing a square (Say, REPEAT 4 [FD 50 RT 90])
Now turn 30° left.
Draw another square.
Now turn another 30°.
Draw another square.
Now turn another 30°.
Draw another square.
Now turn another 30° and so on until you get back to where you started.

Now this is really: REPEAT 12 [REPEAT 4 [ FD 50 RT 90] LT 30] (hint: 12 x 30 is 360)

Why not experiment with other turns, other sizes, other shapes.....other...?

You might also want to experiment with changing the colour of your pen:

PENCOLOUR (abbreviation PC). You need to tell this primitive how much
[Red Green Blue] to mix to make your pencolour.

Try [255 0 0] - and start drawing. Was it what you expected?

N.B. 255 is the largest amount of any colour you can use.

SHOW PC tells you what pencolour you are using.
