I used Canva to create a poster for my co-op with types of quadrilaterals. It's super easy to use and you can create almost anything. Let me know what you like and what do you dislike (about Canva or my design)!

Sydney! I love the colors and these are probably the cutest shapes I've ever seen. The descriptions are really detailed and just awesome. Great job!
