this is a school assignment, for anyone who may have just run into this while browsing scratch. You should go check out one of my projects I made of my own accord, like https://scratch.mit.edu/projects/731959272 , where I explain things like polar coordinates. If you're my grader, I have some experience on Scratch, so I thought I would put it to use. Just click the green flag and the slideshow will start. Click for the next slide, and hold down the mouse to just see the drawing.
