There's inconsistency in the library between plate or tile on the description of these parts. Our general rule would say use "Plate" since the studs are up. Everyone else, including LEGO, calls these Tiles.

In this case think we should use Tile as it more aligns with usage and the community.

Yep, these are Tiles for sure. (Thus they are also all Plates, but we can be more specific…)

The defining characteristic of a Tile is that studs are absent where we'd otherwise expect them to be. In this case, what's absent are the anti-studs, so that's what makes them Inverted.
