Miter and butt are examples of what?

• A. Casing joints
• B. Panel joints
• C. Dowel joints
• D. Frame joints

Answer: (A)

The main idea here is how trim around doors and windows is joined. Miter and butt joints are common methods used when installing the door or window casing. A miter joint is cut at a 45-degree angle on each piece so the two pieces meet neatly at a corner, giving a clean outside edge on the casing. A butt joint simply has one piece ending against another, which is quick and straightforward for running casing along a wall and meeting the jamb. These joints are typical of casing work because they finish the trim around an opening rather than forming the full panel fabric or a structural frame. Panel joints are for panels, dowel joints are used to align pieces with pins, and frame joints are involved with the structure of a frame—not the trim around openings.
