Your goal here is to make a block that draws a five-pointed star. This should
be very similar to the blocks you’ve written previously to draw pinwheels and
polygons. The main difference is that by the time the turtle has drawn the
complete star it will have turned all the way around twice, so 2 x 360 or 720
degrees. So the basic recipe is to move some number of steps, turn one fifth
of 720 degrees, and repeat that five times. That should put the turtle back
where it’s started having drawn a star. Name your block draw star
and have it take one input which specifies the length of the lines that make
up the star.
