I found this prezi on how ballet is related to geometry and I found it useful because it also talked about angles and symmetry and those are related to geometry somehow. I decided to use it since it’s getting harder to find more resources about geometry in ballet. This prezi explained the use of angles in ballet. It also explained how choreographers use angles and shapes to make their dances more interesting and appealing. And as a dancer geometry in dance is very appealing especially if you are in the audience and you don’t know what happened in the process of creating the dance.
