To make a Koch snowflake: Start with an equilateral triangle that has side lengths of 1. This is step 1.

Replace the middle third of each line segment with a small equilateral triangle with the middle third of the segment forming the base. This is step 2.

Do the same to each of the line segments. This is step 3.

Keep repeating this process.
