A Metes and bounds deed begins at a corner marked by a monument and follows a line a given direction and distance to another corner marked by another monument following around and defining the boundary lines of a property. Typically, unless otherwise described or noted, a property corner is placed on the centerline dividing two parcels of land but on the extreme limit of any structure or building located on the boundaries of the property.
In square dance, corner refers to the person you are adjacent to who is not your partner. In standard positioning (boy on the left, girl on the right), this would be for men (or gents) the person standing to one's left, and for ladies the person standing to one's right. In square dance one will often change partners and corners during the course of a dance, in which case one can distinguish between the "original corner" and a "situational corner".
In ice hockey, corners are the curvatures in the rink where the long side boards and shorter end boards meet.
A corner is also used in geography, such as the Four Corners Monument in the United States, marking the corner of state boundary lines.
A corner can also mean a bend in a road or a turn on a race track. Taking a corner better than the other drivers is key in true motor racing, such as Formula One, the World Rally Championship, etc.
In most fighting video games, the edge of the stage is referred to as the "corner," because much like a corner in a wall, it is typically a disadvantageous position, which allows for more combination attacks and makes escaping offensive pressure significantly more difficult.
