Point
A dot in space.
A point is a basic element of geometry and represents a location in space. A point has no size, shape, or dimension. It is typically represented by a dot, and its position is usually denoted by a letter, such as P, Q, or R. In geometry, points are used to define lines, angles, and shapes. Two points determine a line, three points determine a plane, and four points determine a three-dimensional object. Points can be identified and located using coordinates, which are usually given as ordered pairs (x, y) in a two-dimensional space or as ordered triples (x, y, z) in a three-dimensional space.
