How many Counterexamples are needed to disprove the conjecture two lines in a plane always intersect at exactly one point?
To disprove the conjecture that two lines in a plane always intersect at exactly one point, only one counterexample is needed. A single example of two lines that do not intersect, such as two parallel lines, is sufficient to show that the conjecture is false. Therefore, one counterexample is enough to invalidate the claim.
What else can I help you with?
If two lines intersect then they intersect in exactly one what?
If two lines intersect, they intersect in exactly one point. This point is the location where the two lines cross each other in a two-dimensional plane. In Euclidean geometry, two distinct lines can either intersect at one point or be parallel, in which case they do not intersect at all.
Do two distinct planes intersect in a pair of lines?
No. The planes must either coincide (they are the same, and intersect everywhere), be parallel (never intersect), or intersect in exactly one line.
Could three planes intersect in exactly one point?
no
Will the graph of a system of parallel lines intersect at exactly 1 point?
Parallel lines don't intersect, no matter how many of them there are.
Will The graph of a system equation will intersect at exactly 1 point?
A system of equations will intersect at exactly one point if the equations represent two lines that are neither parallel nor coincident, meaning they have different slopes. In this case, there is a unique solution to the system. If the lines are parallel, they will not intersect at all, and if they are coincident, they will intersect at infinitely many points.
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.
Do planes intersect in exactly two points?
No. Either they do not intersect at all, or they intersect in a straight line or are the same.
If two lines intersect then they intersect in exactly one what?
If two lines intersect, they intersect in exactly one point. This point is the location where the two lines cross each other in a two-dimensional plane. In Euclidean geometry, two distinct lines can either intersect at one point or be parallel, in which case they do not intersect at all.
To cross at exactly one point?
To intersect.
Do two distinct planes intersect in a pair of lines?
No. The planes must either coincide (they are the same, and intersect everywhere), be parallel (never intersect), or intersect in exactly one line.
How many Two planes intersect in exactly?
Two distinct planes will intersect in one straight line.
Could three planes intersect in exactly one point?
no
Can two lines intersect in exactly one line?
always
Will the graph of a system of parallel lines intersect at exactly 1 point?
Parallel lines don't intersect, no matter how many of them there are.
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...

The point at which a line and a circle intersect at exactly one point?
Tangent
