SUMMARY
The mathematical definition of direction is established as a ray, which is defined as the part of a line segment on one side of a given point. Direction is not inherently linked to movement or transfer; rather, it is determined by selecting one endpoint of a directed line segment as the base for the ray. The concept of direction is clarified through the understanding that a point divides a segment into two parts, allowing for the selection of either part to define the direction.
