Do you create graphics or are you a homeschooler who is teaching geometry? Here is a super free design tool that you can use in your business or in classroom lessons. Feel like you can't draw a straight line? You can create beautiful designs with the help of the free online Myoats drawing program.
Once you create an image, you can save the design (if you're a member) or download it straight to your computer, even if you aren't a member. Here is a design that I made. It was so easy that even non-drawers could create it. Try out the application here.
By the way, feel free to use this image if you'd like.
