## Sierpinski's Triangle

The fractal we will now draw is formed of a big triangle inside which several smaller triangles are embedded. The prototype of the function to draw it is the following:

    [!java|c]void [/!]sierpinski([!java|c]int [/!]level[!scala]:Int[/!], [!java|c]double [/!]length[!scala]:Double[/!])

Have a look at each world's objective view to understand how to write the function. To draw one side of the triangle, draw a smaller recursive triangle (halve the length) and move forward by the requested length. Globally, you have to draw 3 such sides and turn by 120 between each side.
