Was Pentagon part of the twin towers?

The U.S. Pentagon is a military instillation in Arlington County, Virginia, serving as the Headquarters for the United States Department of Defense. The World Trade Center was a complex of seven buildings in Lower Manhattan, which is part of the city of New York, in the state of New York. This complex featured a pair of two, 110 story high rise office buildings, often referred to as the "Twin Towers" which housed the offices of many international corporations and financial institutions. The two facilities (Pentagon and WTC) are in separate cities in two different states of the U.S., and were not directly connected to one another, except to be important, and iconic symbols of the United States of America.

Both facilities were attacked on September 11, 2001 with three separate hijacked commercial airliners. The Twin Towers of the World Trade Center were both destroyed as a result of the terrorist attack, and the Pentagon was damaged, but has since been repaired. A fourth Airliner was also hijacked on the same day, but crashed in a field near Shanksville, Pennsylvania due to heroic passenger intervention.
