When cutting molding for the outside corner of a baseboard, you should use a

• A. Miter joint
• B. Coped joint
• C. Lap joint
• D. Rabbet joint

Answer: (A)

For an outside corner, a miter joint is the right choice because you cut each piece at a 45-degree angle so the two cuts meet to form a clean 90-degree exterior corner. This creates a seamless appearance on the outside edge and hides end grain nicely. Coping joints are used for inside corners to accommodate wall irregularities by shaping one piece to fit against the other. Lap and rabbet joints aren’t used for typical baseboard outside corners, as they don’t yield the neat 90-degree outside seam required here.
