Miter

Miter, also spelled mitre, is a term with several related uses in carpentry, construction, and ecclesiastical dress. In woodworking and frame construction, a miter joint is formed by cutting each of two pieces at an angle so they join to form a corner. The most common case is a right-angle corner, where each piece is cut at 45 degrees. For other corner angles, the cut angle on each piece is typically half of that corner angle. Miter joints are often used for picture frames, molding, and trim because they create clean, unobtrusive joints.

A miter saw, sometimes called a mitre saw, is a specialized power tool designed to make precise angle cuts in boards and molding. It can be adjusted for different miter angles and, on many models, for bevel angles as well, allowing the user to perform compound cuts. Miter saws are common in cabinetry, carpentry, and finish work, where accurate angled cuts are essential.

In ecclesiastical usage, a mitre is a tall, pointed ceremonial headdress worn by bishops and some higher-ranking clergy. The mitre has two peaks and is typically worn during liturgical functions. Styles and colors vary by denomination and rank, and the mitre is traditionally paired with specific other vestments as part of the ceremonial dress of clergy.
