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! Jared
