A corner is the point or area where two lines, surfaces, walls, or edges meet, creating a change in direction. Corners serve an important purpose in defining the shape, structure, and boundaries of an object, room, building, or space. In architecture and interior design, corners help organize spaces and provide structural support, while in everyday objects they help establish form and stability. Corners can also be used creatively to create storage areas, seating spaces, display areas, or visual focal points.
