Basic Question: Making a geometric star
Hello,
I've recently started programming (Scratch is my first exposure) and am stuck with trying to create a star polygon.
I'm using the <move( )steps> and <turn cw( )degrees> scripts in conjunction with pen/pen down (line drawing).... but am not sure mathematically, which angles to use and how to program the degrees to turn to make a 5-point star (presumably with each side equal in length and each interior angle equal).
Would appreciate any advice on this. Thanks much!

Re: Basic Question: Making a geometric star
You going to want to repeat these steps:
[blocks]
<repeat( 5 )
<move( any number)steps>
<turn cw( 144 )degrees>
[/blocks]
If you accually want it to draw something, you're going to need to use the pen blocks, but 144 is the degree number you want to use.
