👉 Enfolds is a concept in mathematics that refers to the set of all points where two or more lines intersect. It's commonly used in geometry, especially when studying curves and surfaces in three-dimensional space. In this case, it indicates that there are points within an object (in this case, the surface) such that every point on that object is a member of both line segments defined by the objects. This concept can be visualized as if all the lines intersect at the same point, forming
