Community Answer

Yes, but notice that, in the end, the main shape is actually a hexagon. So if you want to make it pentagonal, you need twice as many sides. In your case, 10.

Question

Do I need a ruler to do this?

It's useful to use a ruler so you can keep everything perfect. With that said, you do not need a ruler, just make sure everything is proportional if you want a good triangle.
