Do two planes intersect at a point or a line?
Two planes intersect at a line
What is the slope of a line parallel to a line with slope -2?
For two lines to be parallel they must have the same slope. A line parallel to a line with slope -2 would have a slope of -2.
Which ο¬gure could be the intersection of two planes?
line
What is the line that divides the coordinate plane into two half-planes?
boundary line
Are two lines that lie in parallel planes always sometimes or never parallel?
SOMETIMES. I just did that problem in my California geometry book. They can either be parallel or skew...making the answer sometimes.
What is the two distinct nonparallel planes?
There is no "the" since there are infinitely many non-parallel planes. Two non-parallel planes are planes that intersect in a line.
Do two planes intersects?
two planes intersect in one line, or the planes could be parallel. by the way there is no such thing as skew planes...
If two planes are parallel a line in one plane is parallel to a line in the other plane?
if there are two planes, and they are parallel, then i would assume that their lines are parallel too. so yeh yeh a line in one plane is parallel to a line in the other plane...since they are parallel(:ha * * * * * No. Consider yourself in a cuboid room. The wall in front of you and the wall behind you are parallel planes. There is a line on the wall behind you that goes vertically, from the floor to the ceiling. There is a line on the wall in front of you that goes horizontally from left to right. These two lines are on parallel planes, but the lines are NOT parallel. So, (: ha to the person who answered the question previously!
What is the intersection of two planes?
If there are two unique, non-parallel planes in space, they will intersect, and their intersection will be a line.
Where do two planes intersect?
In geometry, two planes intersect in a line. The only time this is not true is if the two planes are parallel to each other.
Are there always Two planes intersect in a line?
No. Two planes may be parallel and so may not intersect. Also, any line is the intersection of infinitely many planes, not just two.
When two planes intersect do they intersect in a straight line?
Yes. If two planes are not coincident (the same plane) and are not parallel, then they intersect in one straight line.
If two planes are perpendicular to the same line then they are?
...parallel to each other.
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.
How do you draw a line that intersects two nonintersecting planes?
If the planes are non-intersecting, then they're parallel. Any line that intersects one of them intersects both of them.
What are two planes that do not intersect?
parallel 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.
