Another representation utilizes a coordinate graph. Identify enough points to determine a figure on a two-dimensional graph. Now multiply all the coordinates by 2/3 and use the determine a new image figure. The image figure will be similar to the original, with corresponding distances 23 what they were. Thus if there was a segment on the original with length 4/5. then its image will have length 2/3-4/5. Regardless of one's views towards relative merits of representational understanding as compared with skills, properties, or uses, it seems clear that this type understanding is
