Which joint is formed by two surfaces abutting at right angles?

• A. Dovetail Joint
• B. Butt Joint
• C. Stopped Housing Joint
• D. Mitre Joint

Answer: (B)

When two pieces meet so that their contacting faces form a perpendicular corner, you’re dealing with a butt joint. It’s the simplest way to join two pieces end-to-face (or end-to-end) so the angle between them is a right angle, and it’s typically reinforced with glue and fasteners. Other joints change the way the pieces meet: a mitre joint creates a corner with ends cut at an angle to form a neat external edge, a dovetail uses interlocking shapes for strength, and a stopped housing joint involves a recess to accept another piece rather than just meeting at a right angle.
