How can I properly hang a mirror on a wall to ensure it is secure and stable?

To properly hang a mirror on a wall, first, choose a sturdy wall anchor or bracket that can support the weight of the mirror. Use a level to ensure the mirror is straight before marking the placement on the wall. Drill pilot holes into the wall at the marked spots, then insert wall anchors or screws. Finally, hang the mirror securely on the wall using the appropriate hardware.
