Tile installation direction (arrow on the back)

Hello, I have a question about the laying direction of a tile. We have chosen a tile with the dimensions 90x45 and on the back there is a small arrow indicating the laying direction. The tile itself has a natural stone look with a slight structural pattern running longitudinally. Now the question arose whether the tile can be halved so that a half tile can be used to start the row. The remaining piece would then be laid at the end of the tile row rotated by 180°. We cannot see any pattern or direction-dependent surface structure on the tile that would argue against this approach. Is this arrow always present on a tile even if it is not absolutely necessary? Thanks in advance for an answer.

The remaining piece would then be laid rotated by 180° at the end of the row of tiles.

That only sounds logical to me if the rows are calculated to be an integer number of tiles long.

Why shifted by 180 degrees? The direction remains the same.

Exactly, and you don't want to see the cut edge either.

Thank you for your answers. You are of course right, in one row of tiles I don't need to rotate the cut pieces. However, we also have the situation in the hallway that every second row starts with a half tile. Then, of course, one half must be rotated so that the cut edge is not visible.

But we also have the situation in the hallway that every second row starts with half a tile.

Just read my post #2 again. I stick to it: if the rows are not exactly n.0 or n.5 tiles long / "wide", you have a flaw in your thinking.
