WebMedullary rays are cellular structures found in some species of wood. They appear as radial planar structures, perpendicular to the growth rings, which are visible to the naked eye. In a transverse section they appear as radiating lines from the centre of the log. In an axial section they may appear as a variety of transverse markings ... WebA ray starts from a point and goes to infinity. A line has no end points. A line segment has two endpoints. A line segment connects both endpoints.

WebTwo lines (on the same plane) are either parallel or they will meet at a point of intersection. A line segment is a part of a line with two endpoints. A line segment starts and stops at two endpoints. A ray is part of a line with one endpoint and extends in one direction forever. A plane is a flat 2-dimensional surface. WebJun 8, 2024 · A ray extends indefinitely in one direction, but ends at a single point in the other direction. That point is called the end-point of the ray.
