### Koch snowflake

The Koch snowflake is a mathematical curve based on the Koch curve published in a paper by the Swedish mathematician Helge von Koch.

We begin the construction of the Koch snowflake with a equilateral triangle and then make these three steps recursively:

1. Divide each line segment into three line segments with the same length;
2. In the middle line segment, we draw an equilateral triangle;
3. We erase the base of this equilateral triangle.
