I agree wholeheartedly with what you say. Just a small point on the side: The
angles formed by the transversal are corresponding in the same sense. Draw
another transveral to meet the first above the two parallels, and you have
similar triangles with corresponding angles as they should be. The word just
means "in the same relative position".
