Arris refers to the sharp edge that forms when two surfaces meet at an angle, typically in construction or woodworking. There are several synonyms for arris, including bevel, chamfer, miter, and facet. A bevel is an angled cut made along the edge of a material to create a slope. A chamfer is a beveled edge that is cut into the corners of a material to remove the sharpness. A miter is an angled joint made by cutting two pieces of material at an angle and joining them together. A facet is a flat surface on a three-dimensional object that usually has angles or curves. These synonyms of arris are important to understand when working in construction and woodworking industries.
