The Koch snowflake (also known as the Koch curve, Koch star, or Koch island) is a fractal curve and one of the earliest fractals 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.
The Koch snowflake can be constructed by starting with an equilateral triangle, then recursively altering each line segment as follows: 1. Divide the line segment into three segments of equal length. 2. Draw an equilateral triangle that has the middle segment from step 1 as its base and points outward. 3. Remove the line segment that is the base of the triangle from step 2.
