Default Any summary list for scale family?

Sorry this might be a dumb question. As the title asked, Is there a list of scale family for random variables so that I don't need to prove them one by one?

Just make sure I stated clearly.
scale family is: if Y~ some distribution then cY ~ the same distribution as well (e.g. exponential), where c is a constant.

Thanks in advance!

Any time you see theta as a parameter on the SOA tables, it's a scale parameter.

Except for Inverse Gaussian.
