Question

Is there any way to write a proof describing how two couches, one normal size and one scaled down model, are similar? If so, can anyone help to tell me how?

Answer 1

You sort of proved it in the question. If one couch is a scaled down version of the other then they are similar by definition.

Answer 2

Ok, I guess I could say that, but I think the question was looking for like an actual two column proof. But thank you!
