miter joints

Forty-five degree cuts

Miter joints are corners formed by cutting two pieces at matching angles—typically 45 degrees each—so they meet to form a 90-degree corner.

Common in picture frames, door casings, and crown molding, miter joints create clean corners without visible end grain: The frame's miter joints were tight and seamless.

Also spelled mitre joints in British English.
