ht outline transparent areas in one file and select the same in another?

Sorry for the confused sounding subject!

From a png of a whole dollar bill (A) I made a png of a dollar bill torn in half (B) where the other half is gone/transparent. Now, I'd like to make a third file based on these two of the exact *other* half of the dollar bill. i.e., keep everything in A that is transparent in B, and delete everything in A that is not transparent in B.

I'm thinking, "Select the transparent area of B (how?), select that same shape in A (how?), invert the selection, and hit delete."

Thanks for any help/suggestions-

Open the half note image

Open -> As-Layers a full note image

Make sure the full note layer has an Alpha channel. Layer -> Transparency -> Add Alpha Channel

On the half note layer: Layer -> Transparency -> Alpha to Selection screenshot 1

On the full note layer Edit -> Cut screenshot 2

Turn off visibility of half note layer, Export as a png.
