What is the key difference in orientation between alpha and beta anomers?

Alpha anomers have the hydroxyl group directly above the highest numbered carbon, while beta anomers have it directly below.

Alpha anomers have the hydroxyl group on the same side as the highest numbered carbon, while beta anomers have it opposite.

Alpha anomers have the hydroxyl group opposite to the highest numbered carbon, while beta anomers have it on the same side.

Alpha anomers have the hydroxyl group directly below the highest numbered carbon, while beta anomers have it directly above.
