The Koch snowflake (also known as the Koch curve, Koch star, or Koch island) is a mathematical curve and one of the earliest fractal curves to have been described. It is based on the Koch curve, which appeared in a 1904 paper titled “On a continuous curve without tangents, constructible from elementary geometry” by the Swedish mathematician Helge von Koch. How to construct one: Step 1: Draw an equilateral triangle. You can draw it with a compass or protractor, or just eyeball it if you don't want to spend too much time draw ing the snowflake. It's best if the length of the sides are divisible by 3, because of the nature of this fractal. This will become clear in the next few steps. Step 2: Divide each side in three equal parts. This is why it is handy to have the sides divisible by three. Step 3: Draw an equilateral triangle on each middle part. Measure the length of the middle third to know the length of the sides of these new triangles. Step 4: Divide each outer side into thirds. You can see the 2nd generation of triangles covers a bit of the first. These three line segments shouldn't be parted in three. Step 5: Draw an equilateral triangle on each middle part. Note how you draw each next generation of parts that are one 3rd of the mast one. Step 6: Repeat until you're satisfied with the amount of iterations. It will become harder and harder to accurately draw the new triangles, but with a fine pencil and lots of patience you can reach the 8th iteration. The one shown in the picture is a Koch snowflake of the 4th iteration. Step 7: Decorate your snowflake how you like it. You can colour it, cut it out, draw more triangles on the inside, or just leave it the way it is.
