A ray is a line that has an originating point, but no end.


Is a ray a defined term?

You just defined a ray. ■


Is the term 'ray' is defined?

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.


Does a ray have hundreds of endpoints?

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).


What is the geometric definition of a ray?

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.


Is ray a undefined term?

No !(: its in the dictionary! Look it up!(:


Is a ray CD the same as ray dc?

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.


What does an a ray look like?

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.


Which pair of undefined terms is used to define a ray?

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.


Why is a ray defined?

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.


What is a line that has a straight line and is endless?

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.
