A point has no part. It is an element that has no breadth. Various points make a line. A point is characterised by the absence of dimensions and magnitude. It has no thickness. A point only occupies a space. A point can be defined only by geometric properties. A point in the domain of geometry is represented by various coordinates such as x and y in a two-dimensional plane and by x, y and z in a three-dimensional plane.
