No. Ray= A finite beginning and no finite end. A ray is a linear projection in one direction. If three rays begin at the same point of origin they will never intersect again given their respective directions. Same goes for the situation of them beginning at different P.O.O's; it's only physically possible for them to intersect at one point then after. (Unless of course you bring into the picture mirrors and different mediums wherein the index could possibly cause them to reflect/refract and change their paths.. then they could possibly intersect at more than one point... BUT generally/simply speaking NO three rays cannot intersect at more than one point :-) )
no they can't
two lines intersect at point b which is also end point of two rays
•-------> •-------> or you can do them the opposite ways
any rays that intersect will form 4 angles
Vertex
Rays that are not parallel do not necessarily intersect. Rays have a starting point and if they diverge, they will not intersect. If they converge from their starting point, then they will eventually intersect.
The point at which the rays of an angle intersect is the vertex.
no they can't
Yes.
A point of concurrency is a place where three or more, but at least three lines, rays, segments or planes intersect in one spot. If they do, then those lines are considered concurrent, or the the rays are considered concurrent.
Two collinear rays that do not intersect are called parallel rays. This will only occur for a short time, however, because they will intersect at some point.
It seems there might be a typo in your question. The correct term is "non-collinear rays," which are three or more rays that do not lie on the same line. These rays may intersect at a point or diverge away from each other.
Yes.. More than 3.
no the definition is two lines intersecting once
It means that they are skew.
the vertex
A point of concurrency is a point where three or more lines, segments, or rays intersect or meet. Common points of concurrency in geometry include the centroid, circumcenter, incenter, and orthocenter of a triangle.
