A "corner" is the point where two lines or surfaces meet, forming an angle. In geometry, corners are essential in defining shapes, such as squares and triangles. They can be found in various contexts, from the corners of a room to the edges of a piece of paper. In everyday life, corners can also refer to the intersections of streets, where two roads meet. These corners are important for navigation and traffic flow. Additionally, corners can be used metaphorically, such as in the phrase "backed into a corner," indicating a situation where someone has limited options.
