A point, often represented as a dot, is a fundamental concept in geometry. It has no dimensions—meaning it has no length, width, or height. Points are typically used to indicate a specific location in space and are often labeled with capital letters, such as A, B, or C. In mathematics, points can be plotted on a coordinate system, like the Cartesian plane, where each point is defined by a pair of numbers (x, y). Points serve as the building blocks for more complex shapes, such as lines and polygons, and are essential in various fields, including physics and computer graphics.
