The Koch curve can be constructed by starting with an equilateral triangle, then recursively altering each line segment as follows:
- divide the line segment into three segments of equal length.
- draw an equilateral triangle that has the middle segment from step 1 as its base and points outward.
- remove the line segment that is the base of the triangle from step 2.
The Koch curve is the limit approached as the above steps are followed over and over again.
