Definition Of A Ray Math
The other point is merely a signpost a way to give the ray a name.
Definition of a ray math. In geometry a ray can be defined as a part of a line that has a fixed starting point but no end point. One will be an endpoint the start of the ray. A ray is a part of a line that begins at a particular point called the endpoint and extends endlessly in one direction. A ray has no measurable length because it goes on forever in one direction.
A ray is named based on the direction in which it extends. When naming a ray it is denoted by drawing a small ray on top of the name of the ray. If you draw a ray with a pencil examination with a microscope would show that the pencil mark has a measurable width. On its way to infinity a ray may pass through more than one point.
It has zero width. It can extend infinitely in one direction. How do we name a ray. A ray can be thought of as being a snippet or segment of a line.
A ray is also called half line. A ray is named with its endpoint in the first place followed by the direction in which its moving. A ray is one dimensional. A part of a line with a start point but no end point it goes to infinity try moving points a and b.
