no the definition is two lines intersecting once
wrong!
FALSE!!
it has 4 vertices, a vertice is a point were two lines intersect
corner is a point, where more than two plane will intersect. Example: Cube. Rajasekar-Infotech Bangalore.
Euclid's fifth postulate: If two lines are drawn which intersect a third in such a way that the sum of the inner angles on one side is less than two right angles, then the two lines inevitably must intersect each other on that side if extended far enough.It can be rewritten: If two lines are drawn which intersect a third at angles of 90 degrees, the two lines are parallel and will not intersect each other.It has also been rewritten as Playfair's axiom:In a plane, given a line and a point not on it, at most one line parallel to the given line can be drawn through the point.
Yes.
no they can't
wrong!
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 :-) )
Yes.. More than 3.
FALSE!!
In Euclidean plane geometry two infinitely long straight lines intersect at only one point
Sometimes. Not always.
Curves yes, straight lines no
Converging lens refers to a type of lens that is thicker at the center than at the edges, causing light rays passing through it to converge to a focal point. This focal point is where the light rays intersect after passing through the lens, creating a real image.

No, two distinct planes in three-dimensional space cannot intersect at just a single point. They can either be parallel and not intersect at all, or they can intersect along a line. If they intersect, the intersection will always be a line rather than a single point.
