The classic king and rook checkmate works by taking opposition to force the enemy king toward the edge, rank by rank. It is slow but reliable. A key waiting move. Black must either walk into opposition (allowing a rook check), retreat to the back rank voluntarily, or let White chase the king to the edge.

White uses the rook check to exploit the opposition and force the enemy king backward. This concept is critical in many endgames, especially king and pawn endings.

Practice time! Use the box method: cut off the king with your rook, take opposition with your king, then push rank by rank. This is harder than K+Q, take your time.
