@mirthfulostrich Sorry, the screenshot happens to be from Module 3 just because I had made it before in response to someone else's question, but the lesson you are asking about is in Module 2: Geometry Tools. So don't worry about stealing anything. The link goes to the course lesson, not to a forum post. Please see the link above! 🙂

@divinedolphin Wow, that's a really old typo... thank you so much for finding this. We'll put it on our to-do list to fix at some point. 🙂
