Skew lines are non-coplanar, which means they are in different planes. Skew lines are in different planes and they do not intersect.
None.
Yes, there are three ways that two different planes can intersect a line: 1) Both planes intersect each other, and their intersection forms the line in the system. This system's solution will be infinite and be the line. 2) Both planes intersect the line at two different points. This system is inconsistent, and there is no solution to this system. However, both planes will still be intersecting the same line, albeit at different locations on the line. 3) Both planes intersect each other, but their intersection does NOT form the line in the system. However, if the line in the system intersects the planes' intersection, then they will all intersect a single point. The solution will be finite and be a single point. There are also 3 ways two different planes WON'T both intersect a line. 1) The two planes and the line are all parallel to each other, and none of them intersect each other. 2) The line is parallel to one plane, but intersects the other plane. 3) The same as #2, but now the line is parallel to the other plane and intersects the one plane.
skew lines
four.
No it was not till 1903 that planes were invented No it was not till 1903 that planes were invented.
i do not now
There a number of different RC Planes around now days. I am not sure what the exact number is but, just guessing I would say lest 25-50 different types of planes now a day are being tested for our military capability.
it is different because now women are as strong as men when it comes to flying planes
The airplane wasn't invented until 1903, so no.
that's the same thing.
Planes have large wings, Helicopters have rotors
who first flew? wright bros? the year was 1903, so maybe 106 yrs
After many years of tries, the first powered airplane flight was in 1903 by the Wright brothers.
Only jet fighter planes break sound barrier now.
the plane that was highest were the spy-planes 60,000ft!!
Absolutely. Well, actually that depends what you consider a "normal airplane," however, fighters are very different from most other planes.
