No. Any pair of the three will describe a plane, so the three possible pairs describe three planes.
no
No, 2 planes may only intersect at a line, a plane, or not at all. THREE planes may intersect at a point though...
yes, three planes can intersect in one point.
This is true. If three straight lines are drawn, they can only intersect at two points. That is, each line will only intersect with another once.
there are three methods: combination, substitution and decomposition.
collinear plane
no
No they can be Collinear - Points that lie on the same line.
It's possible, but for any three lines in the same plane, there could be ether one point of intersection (unlikely) or three (more probably).
No, only three lines can intersect at a single point.
its the point of concurrency
concurrent lines
concurrent
Three or more straight lines in a plane such that they intersect pairwise.
Any number of lines can intersect all at the same point. Think of a circle. Now think of all of its diameters.
Yes, in Euclidean geometry, an infinite number of lines can meet at one point.
No. If they are parallel, then a plane exists which both lines lie in. Skew lines can not be on the same plane.
