Pencil Code: Lesson on Angles

Here is a lesson on Angles using Pencil Code. It talks about why a triangle can be made with 120 degree angles. Using concrete turtle programs, it teaches the mathematical concepts of exterior and interior angle, arcs, and regular polygons. And it provides a hint for exploring curves with winding number larger than zero.

No written companion materials yet, but when they are ready, I will update this blog post.
