Which of the following is NOT a common style of hinge door?

The reason sliding panel is not a common style of hinge door is that sliding panels operate on a different mechanism than traditional hinge doors. Hinge doors typically swing open and closed on a pivot point provided by the hinges, allowing them to occupy a certain space when opened. Sliding doors, however, do not swing; instead, they glide along a track, making them functionally different from hinged doors.

In contrast, the other options listed—flush panel, raised panel, and glazed doors—are all types of doors that utilize hinges. Flush panel doors have a flat surface and can swing open, raised panel doors have a decorative raised surface that also swings on hinges, and glazed doors incorporate glass panels into their design, yet still function as hinged doors. Understanding the distinctions in operation helps clarify why sliding panels do not fit the conventional definition of a hinge door.
