The most basic building block of all geometric figures is simply the point. A point has no size or dimension but it does have a location. Lines are made up of a series of points.
The geometric term for the tip of a pen is a "point." In geometry, a point is a location in space that has no size or dimensions, represented by a dot. It is the most fundamental element in geometry and serves as the building block for all geometric shapes and figures.
