Polar coordinates and similarity were used to construct Mt. Rushmore! 
The sculptor made a small model of 4 faces.  On top of each head was
placed a "ruler" with a string on the end and a weight.  The ruler
would be swung out a given number of degrees and the then the
distance, to say the end of Lincolns nose would be measured.  Then on
the actual mountain, they had a BIG ruler/piece of wood and they would
decide how much to detonate/drill by using the same degrees and
distance.

Sounds like r and theta to me!
