Indeed  it seems to me that as stated, the thing _is_ a (non trivial) translation  I reckon there is something clockwise in the question (as stated) that should be counter clockwise ('cos when I change it, it does work). (for fun: what happens when you replace the triangle by a polygon, and the order of rotations by some permutation of the order?)
