They are similar because both of them are perfectly straight. The only major difference is that lines never end and rays start from a specific point.
it dont have similarity
Rays aren't really lines, since (Euclidean) lines extend infinitely in all directions, so they can't be parallel lines. But that's to fret a bit too much over the wording. Yes, rays, just like lines and line segments, can be parallel to other rays, lines, or line segments.
No , Lines of Latitude and Longitude are not rays because they do not go on infinitely (forever). They are only imaginary lines that exist on Earth.
The rays representing the sound emitted by a siren spread out in all directions from the source, similar to how gravitational field lines spread out from a massive object. Both the sound waves and gravitational field lines follow an inverse square law, where the intensity weakens with distance. This causes them to resemble rays that diverge from a central point as they travel outward.
segments, lines, and rays.
common point of two rays or lines, note: rays and lines are the same thing!!
We might consider gamma rays similar to X-rays. Both are at the top end of the electromagnetic spectrum, with gamma rays generally a bit higher in frequency (though there is a bit of overlap). Some might argue that ultraviolet rays, which are a bit lower in frequency than X-rays, make them similar. But we generally consider X-rays and gamma rays "most" similar as both are forms of ionizing radiation because the energy of the photons is so great.
They can be, and are, "skew". If they are not lines, they cannot be "skew lines".
Concurrent lines.
Skew lines, parallel lines or an angle.
