Michael Reid -- i found 5 solutions to rodolfo's  L  tromino dissection.  this doesn't include fractal solutions, of which there are infinitely many.
Rod G Bogart -- So, I have two answers, but one of them is a fractal.  The first is the simple triangle dissection on the right below, and the
other is the fractal division as shown on the left.  The lower sawtooth figure is twice the area of the upside down sawtooth figure.  Dunno if this really qualifies, but I like the idea of a fractal shape being similar to a larger fractal shape.

Erwin Eichner sent in the triangle solution as well.
