Congratulations, you have successfully illustrated the Geometric aspects of
the Brooklyn Bridge. You should be proud that both New York City and the
Brooklyn Bridge have a special place in American history. Now, you should
have a better appreciation of the mathematical aspect of the bridge.
Without mathematics, there would be no Brooklyn Bridge and a piece of New
Yorks history would have never been written. In addition, you know a real
life application of mathematics.
Still wondering why Math is important for bridges. Copy and paste this web
site into explorer and see if your bridge can withstand an earthquake.
