Which joint has half the wood cut away on one side?

• A. Half lap joint
• B. Halving joint
• C. Mortice and tenon
• D. Bridle joint

Answer: (A)

A half-lap joint is formed by removing half the thickness of the material in the joint area on each piece so that when the two pieces overlap, the outer faces line up flush with the thickness of a single piece. This approach matches the idea of “half the wood cut away on one side,” because only half of the thickness is removed in the joint section, allowing the pieces to interlock while keeping a smooth, level surface. It’s commonly used for frames and supports where you want a strong, flat intersection without widening the overall profile. The other joint types involve different ways of shaping the ends (a mortice and tenon uses a mortise and peg; a bridle joint uses a through-tenon; a halving joint cuts the ends to half-thickness to meet).
