Technique for Inside and Outside Corners

Inside Corners:

Cut the drywall sheets at a 45-degree angle.
Apply corner bead along the inside corner, securing it with screws.
Apply joint compound to the corner bead and smooth it with a corner trowel.

Outside Corners:

Cut the drywall sheets straight and abut them against each other.
Apply corner bead over the joint, wrapping it around the outside corner and securing it with screws.
