Does two intersecting planes always sometimes never intersect in exactly one point?
Never.
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.
What does dihedral angle mean?
A dihedral angle is the angle between two intersecting planes.
Could three planes intersect in exactly one point?
no
What would serve as a counter example to the statement Two planes intersect in exactly one line?
Two planes do not intersect at all if the planes are parallel in three-dimensional space.
Does two intersecting planes always sometimes never intersect in exactly one point?
Never.
If two planes intersect then the intersecetion is called?
A line, or intersecting planes.
What are two planes that intersect in a straight lines known as?
Intersecting planes!
If two planes intersect then their intersection is a line Two planes are intersecting?
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.
How many Two planes intersect in exactly?
Two distinct planes will intersect in one straight 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...
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.
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.
What does dihedral angle mean?
A dihedral angle is the angle between two intersecting planes.
Do Two planes always intersect in a line?
Some planes are parallel and don't intersect at all. Those that do intersect (and that are not coincident, i.e. the same plane) intersect in a line.
Could three planes intersect in exactly one point?
no
