no pun in ten did
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.

On the Cartesian plane (0, 0) is the point of origin where the x and y axes intersect each other at 90 degrees.
The coronal plane shows brain structures as they would be seen from the front. This plane divides the brain into front and back portions.
The midsagittal plane divides the brain into equal right and left portions.
Frontal Plane or Coronal Plane
The brain is divided into unequal right and left portions by the sagittal plane. This plane passes from front to back, dividing the brain into two hemispheres - the left hemisphere and the right hemisphere.
Your brain. -Correction, brain is incorrect. The Urinary Bladder is divided in half by the median (sagittal) plane.
the plane crashed
The midsagittal plane divides the right and left sides of the brain into two equal sections. A plane divides the body into two equal sides.
Hijacked
