No, I wod say scaling is any diagonal matrix and thus even includes mirroring.

Cool, now explain that to a class of 7th graders for me

edit: raised grade, it may been set a low but it varies. I think most kids start to learn this stuff in/around middle school

edit 2: also mirrored objects are generally considered similar so that's fine
