The star is made from squares.

What is the amount of turn between each square?
The turn is 45 degrees because there are 8 squares.

How can you be sure that you are in the right place to start to draw the next square?
Each square starts at the opposite corner to the starting point of the previous square - this can be achieved by drawing one and a half squares each time.

You can use the REPEAT command to speed things up. For example:

REPEAT 4 [FD 40 RT 90] draws what?

You will know if you have the correct solution because you will be able to create the pattern in the picture!!
