InheritanceRay Inheritance Object
Implements Geometry

This means half of a line, it is infinite in one direction, but ends at a certain point in the other direction. In Euclidean geometry, a ray (or half-line) given two distinct points A (the origin) and B on the ray, is the set of points C on the line containing points A and B such that A is not strictly between C and B. In geometry, a ray starts at one point, then goes on forever in one direction : (A) -- (B) -- ((C)) -- >
