… when an object cannot be scaled without using the power law. It is self-similar, because after scaling, it can be turned back into its original by squaring.

… when regardless of the size of an object the same principle (e.g., proportion) will hold. It is self-similar, because after scaling, it can be turned back into its original by applying the power law.

… when an object's proportions vary with size. It is self-similar, because after scaling it still looks roughly the same.
