Yes.
I don't know which one you consider to be the third one, or what this question has to do with math. Two of the planes were crashed into the World Trade Center. One plane was crashed into the Pentagon although, based on its flight path, its original target is believed to have been the White House but they apparently couldn't find it. The other plane was presumeably intended for the Capitol but the passengers attacked the hijackers, attempting to retake the plane. It crashed in rural Pennsylvania.
If the two lines are coplanar, then it is a third, parallel, line which is halfway between the two lines. If the two lines are not in the same plane, then I think it will be a saddle shape (paraboloid).
The third line is known as a transversal.
It's a third line, parallel to both and midway between them.
Parallel lines.
Yes, they are.
We don't think so. We reasoned it out like this: -- Two planes either intersect or else they're parallel. -- If two planes intersect, then they're not parallel. -- In order for the third one to avoid intersecting either of the first two, it would have to be parallel to both of them. But if they're not parallel to each other, then that's not possible. If the third plane is parallel to one of the first two, then it's not parallel to the other one, and it must intersect the one that it's not parallel to.
Yes. Provided the first two planes are parallel, the third plane can be arranged so that it intersects both of the others.
The third plane went into the Pentagon.
They are parallel to each other.
Yes.
Two planes hit the Twin Towers of the World Trade Center in New York. The third plane hit the Pentagon and a fourth plane was supposed to hit the White House or Capital, but crashed in a Pennsylvanian field.
There are three axes in any spatial body. X,Y and Z. You have three planes in human body. You have sagital plane. ( Sagita means arrow. So it goes like arrow.) Transverse plane means horizontal plane, when you are standing upright. There is third plane called coronal plane, perpendicular to these two planes.

Four passenger planes were hijacked by terrorists in order to be used for suicidal attacks. Two of those were crashed into the North and South towers of the World Trade Centre. The third plane was crashed into the Pentagon, while the fourth plane crashed in a field near Pennsylvania.
All four planes were originally headed for cities in California (Los Angeles, and San Francisco). The first hijacked plane was diverted into the North Tower of the World Trade Center in New York, and the second plane flew into the South Tower on live television. The third plane crashed into the U.S. Pentagon Headquarters of the Department of Defense. The fourth plane was headed for an undetermined target in the Washington D.C. area, but resistance from the passengers, who had learned of the fate of the other hijacked planes through cell phone conversations, caused the hijackers to crash in a nose-dive fashion into a field near Shanksville, Pennsylvania.
