The term 'PART OF A BASKETBALL HOOP' can be broken down into two parts: the RIM (3 letters) and the NET (3 letters). The RIM is the metal hoop that is attached to the backboard and is used to shoot the basketball through. The NET is the piece of fabric that hangs from the RIM and is used to catch the ball when it goes through the hoop. Both the RIM and the NET are essential components of a basketball hoop and are necessary for playing the game.
