Which is a simple joint where two pieces butt together at right angles?

• A. Butt Joint
• B. Housing Joint
• C. Dovetail Joint
• D. Dowel Joint

Answer: (A)

The key idea is recognizing the simplest way to make a right-angle connection by joining the end of one piece against the face of another. A butt joint is formed when two pieces are cut square and simply placed together at a corner, then secured with glue and/or fasteners. It’s the most straightforward method for creating a right-angle frame or box because it doesn’t require shaping complex profiles or interlocking parts. It’s quick to make, but its strength comes mainly from the glue and fasteners or from reinforcing methods added later. In contrast, a housing joint creates a recess for one piece to fit into, a dovetail interlocks like puzzle pieces for high strength and resistance to being pulled apart, and a dowel joint uses pins for alignment and strength. So, for a simple right-angle connection, the butt joint is the best fit.
