Which joint is used at corners and for splicing long runs?

• A. Miter
• B. Butt
• C. Dado
• D. Rabbet

Answer: (A)

A miter joint is formed by cutting the ends of the pieces at an angle (typically 45 degrees) so they meet to form a clean, true corner. This style is ideal for trim and molding because the joint creates a nearly invisible seam along the corner and along splices in a long run, giving a continuous, elegant line. When you need to extend a long piece of trim, a mitered end-to-end splice keeps the visible seam small and helps preserve the appearance of a single long piece. Other joints serve different purposes: a butt joint simply squares the ends together without any angle, which leaves a noticeable seam at corners and along runs. A dado is a groove cut across the grain to accept a panel or shelf, not suited for corners. A rabbet is a notch along the edge to receive another piece, also not used for creating corner seams or long-run splices.
