Ray means each of the lines in which light and heat seem to stream from the sun or a body which is luminous, or pass through an opening which is often small.
A ray can be identified as a straight line that starts at a specific point, called the endpoint, and extends infinitely in one direction. It is typically represented in diagrams with an arrow at one end to indicate its unending path. To spot a ray, look for a line segment that has a defined starting point but no endpoint on one side.
ray ray is no where ugly :)

Ray Ray has a lisp
A ray is a line that has an originating point, but no end.
Yes it is
You just defined a ray. ■
In mathematics, a ray is defined as a part of a line that has one endpoint and extends indefinitely in one direction. It is represented by a single point and an arrow indicating the direction of the line.
A ray is defined as having an origin but no endpoint (unless you count the origin as an endpoint, in which case it has 1).
Strictly speaking, a "ray" is in the family of lines and line segments. A line is defined as a one-dimensional object of infinite length with no well-defined endpoints (since "infinity" isn't a well-defined value). It's the 1-D analogue to a plane or a space. A line segment is the finite equivalent of a line. A ray is a bit stranger: it's infinite in length, but has one well-defined end-point, where the ray originates. They show up a lot in classical optics because if nothing interrupts it, a light ray is created at some point and then continues forever.
No !(: its in the dictionary! Look it up!(:
No, ray CD and ray DC are not the same. A ray is defined by its starting point and extends infinitely in one direction. Ray CD starts at point C and extends through point D, while ray DC starts at point D and extends through point C, thereby having different directions.
A ray is a straight line that starts at a point and extends infinitely in one direction. It has a defined endpoint but continues on forever in the direction it points. A ray can be represented with an arrow pointing in the direction of its extension.
A ray is defined using the undefined terms "point" and "line." A ray consists of an endpoint (a point) and extends infinitely in one direction along a straight line. The combination of these two concepts allows us to describe the characteristics of a ray in geometry.

parallel ~ Actually, all lines are straight and endless. A ray has one endpoint, is straight, and the other end of the ray is endless. A segment has a defined beginning and end, and is straight.
