When two or more lines intersect at a point they are said to be?
Theorem: If two lines intersect, then exactly one plane contains both lines. So, when two or more lines intersect at one point, they lie exactly in the same plane. When two or more lines intersect at one point, their point of intersection satisfies all equations of those lines. In other words, the equations of these lines have the same solution, which is the point of intersection.
When does a plane and line intersect at one point?
When the line is inclined to the plane. That is, it is not in the plane nor is it parallel to it.
If two lines intersect then they lie in one plane. Is this true always sometimes or never?
always. if two lines intersect, then exactly one plane contains the lines.
Does a plane and a line intersect at most in one point?
yes
Does a line always intersect a plane at one point?
yes
If two planes intersect do they intersect in exactly one plane?
No, two planes do not intersect in exactly one plane unless the planes are exactly overlapping, making one plane. In Euclidean Geometry two planes intersect in exactly one line.
Two planes can intersect on exactly one point?
No, 2 planes may only intersect at a line, a plane, or not at all. THREE planes may intersect at a point though...

Three planes may all intersect each other at exactly one point?
Three planes may all intersect each other at exactly one point. This commonly occurs when there is one straight plane and two other planes intersect it at acute or obtuse angles.
To cross at exactly one point?
To intersect.
What is a tangent internally?
Two circles in the same plane are externally tangent if they intersect in exactly one point and their intersection of their interiors is empty.
A plane and a line intersect at most in one point?
Yes, except when the line is in the plane. In the latter case, they intersect at each point on the line (an infinite number).
When does a plane and line intersect at one point?
When the line is inclined to the plane. That is, it is not in the plane nor is it parallel to it.

Does a plane and a line intersect at most in one point?
yes
Does a line always intersect a plane at one point?
yes
The point at which a line and a circle intersect at exactly one point?
Tangent
