Points form lines, lines form surfaces, and points are the most basic components in geometry. Generally speaking, points are regarded as zero-dimensional objects, lines as one-dimensional objects and surfaces as two-dimensional objects. Points become lines, and lines become faces.

1, a center or an origin can be called a point, and a point is a unit; 2. Two points determine a line, and the distance between two points is called a straight line; 3. Three points determine a plane, and the shape formed by connecting three points with a straight line is called a plane;
