Geometric Ray

We know that, a ray is an important topic of line, and geometrical chapter in mathematics subject. In mathematics, a ray is defined as several ways, when we have seen a vector, a ray vector is going to one point to other point, and it is called as rays. In this geometrical part, ray is used in mostly as the lines and it’s relevant. In this article we are going to explain about the geometric ray, and its definitions.

Definition of the Geometric Ray:

Generally a ray is defined as many ways; it is one part of line.
It has a straight line with one end point and other direction (side) extends to infinity.
And a ray is start with end point, and then other point on the ray next.

For example:

Picture representation for geometric ray:

Geometric rays

If suppose the above ray (figure) is vector ray means, a ray is vector (xy) form of point x to point y.
And a ray is start with end point x, and other side goes to infinity on next. It is named ray.

Note:

If suppose the given ray (see figure) is vector ray means, a ray is vector (xy) form of point x to point y.

Ray is` vec (XY)` .

Exact definition for ray:

Ray is straight line that starts at a point and continues outward in another direction. And a ray is start with end point, and then other point on the ray next.

Examples Pictures and Explain in Geometric Rays:

Example problem 1: Draw a straight line, with two points ray figure.

Figure:

Example problem 2: Draw the both opposite side rays.

The ray figures:

example figure for ray, and    example figure for ray

These rays are mostly used in the sphere intersection problems.

Example problem 3: Draw the angle figure used on 2 ray figures with 1 common end point:

Angle figure in ray:

Example problem 4: Draw the parallel line, and use the ray with intersect (cross) the parallel line.

I am planning to write more post on Line Distance Formula and iseet 2013. Keep checking my blog.

These all above the general explanations and example figures are making clear about the geometric ray definition and concept.
