Text:        That depends on how you measure it.  In 3 dimensions the sphere, 
dome and ellipsoid (submarine shape or egg shape) can withstand very high 
external pressure.  In 2 dimensions a star shaped fortress is the most 
difficult to attack.  The "strongest geometry" depends on the application.

Text:        I was always told from a construction standpoint that the 
triangle is the strongest geometrical figure.  If you notice, most bridges are 
made with "connected" triangles.  Look at the structure of a bridge the next 
time you cross a big river.
