Corner joints are connections used in woodworking and construction to join two pieces of material at a right angle. They are commonly found in furniture, frames, and structures, providing stability and strength. Various types of corner joints include butt joints, miter joints, and dovetail joints, each offering different aesthetic and functional benefits. These joints can be reinforced with adhesives, screws, or dowels to enhance their durability. Properly constructed corner joints help ensure that the overall structure remains square and aligned, which is crucial for both appearance and functionality in projects involving woodworking or carpentry.
