Answer:

A fractal is a curve which has the same degree of regularity no matter at what distance or magnification it is viewed.

One of the simplest such curves is the Koch snowflake curve, named after the Swedish mathematician Helge von Koch who first described it in 1904. To see how it is formed, start with an equilateral triangle, then construct equilateral triangles on the middle third of each side as shown, to form a six-pointed star. Now construct equilateral triangles on the middle third of each side of the star, and continue the process indefinitely.

Fractals are commonly used in computer-generated graphics.
