A mitre joint (British spelling) is created when two pieces of material, commonly wood, are bevelled at identical angles and joined to form a corner. Often, these angles are 45 degrees each, resulting in a 90-degree corner. Mitre joints are commonly found in picture frames, mouldings, and wherever a seamless corner is desired. Unlike a butt joint, a mitre joint hides the raw edges. Think of it as a secret handshake between two pieces. The success of the joint lies in precise angles.
