Coordinates, in Mathematics, are measurements that fix the position of a point, line, area, or volume, Thus, the position of a point on this sheet is determined if we know its distances from the top edge and from the left-hand-side edge. So, also, a point in a room is found when we know its distances from the floor and from two walls that meet each other. The discussion of the properties of figures by investigating the coordinates of their constituent points belongs to Coordinate Geometry.
