What type of joint is typically used to connect two framing members at a right angle?

A corner joint is specifically designed to connect two framing members at a right angle, which is commonly seen in the construction of walls, frames, and furniture. This type of joint allows the two members to intersect securely, providing structural integrity and stability to the assembled piece. In construction, achieving a strong connection at right angles is crucial, and corner joints are often reinforced with fasteners or adhesives to enhance their strength.

In contrast, while a lap joint and a butt joint can be used in various framing applications, they do not inherently connect two members at a right angle as effectively as a corner joint does. The mortise and tenon joint is a more complex connection typically used for stronger structural joints in furniture and cabinetry rather than standard framing applications, and it also does not specifically apply to connecting two members at a right angle in the same straightforward manner as a corner joint. Thus, the corner joint's design makes it the ideal choice for this specific need.
