A basketball backboard is a flat, rigid, vertical board with an attached basketball hoop and net, used in the game of basketball. Backboards are typically rectangular and made of materials like Plexiglas or tempered glass, chosen for their durability and ability to withstand impact. They serve as a surface to rebound the ball off of, aiding in scoring and preventing shots from going out of bounds.
