👉 Presecular is a concept in mathematics and physics that refers to the idea of a "point" or "line" that lies on both sides of an object (like a line segment) but not at its endpoints. The presecular point is considered to be the center of rotation for the system, which is why it's often used as the starting point for rotations. In simpler terms, presecular points are the points at which two lines meet each other without intersecting or overlapping.
