Answer»

point

In classical Euclidean geometry, a point is a primitive notion that models an exact location in the space, and has no length, WIDTH, or thickness

line

In geometry, the notion of line or straight line was introduced by ancient mathematicians to represent straight objects with negligible width and depth

Ray

In optics a ray is an IDEALIZED model of light, obtained by choosing a line that is perpendicular to the wavefronts of the ACTUAL light, and that points in the direction of energy flow

line SEGMENT

In geometry, a line segment is a part of a line that is bounded by two DISTINCT end points, and contains every point on the line that is between its endpoints
