Yes. If two planes are not coincident (the same plane) and are not parallel, then they intersect in one straight line.
Lines that have one point in common are said to intersect one another at that point. Almost all straight lines of infinite length intersect one another, unless they are parallel to each other.
Two lines with one point in common are said to intersect at that point. Any two straight lines with infinite length will eventually intersect each other, unless they are parallel to each other.
A system of equations will have one solution if the graphs of the lines intersect. This is because the lines intersect at a single point. Let's say that point is (a, b). The x = a, y = b is the one and only solution for the system.
Tangent circles.
If the rays do not intersect at one point, it indicates that they are either parallel or diverging from each other. In geometry, parallel lines do not intersect at any point, while diverging lines move away from each other indefinitely.
no they can't
no the definition is two lines intersecting once
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 :-) )
If two different lines intersect, they will always intersect at one point.
Point.
yes, three planes can intersect in one point.
If two circles intersect then they have to intersect at two points.
No, two straight lines can intersect at only one point and that is their point of intersection.
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.
wrong!
Perpendicular rays are two rays that intersect one another to form four right angles. Below is an image that shows two perpendicular rays.
