This is a fantastic thought and it highlights how it can be tough to put a hard fast rule on differentiating the two ways of thinking of ratios based on units. When comparing sides in a single triangle, we’d be thinking multiplicative comparison… however when enlarging / shrinking triangles to other similar triangles, A composed unit feels more appropriate. Great eye here.
