# Module Two Post Four (Mathematics of Dance)

This PDF talks about the mathematics of dance. I only focused on the symmetry portion which actually had a lot of good information. It talked about how Choreographers use
symmetry as a stylistic feature in their dance creations. It also said that in dance all 4 of the  symmetries are used. Reflectional, rotational, translational and
glide reactional symmetry.

# Module One Post Thirteen (The Geometry of Ballet)

This is another prezi on geometry and ballet it’s similar to the last prezi I used: https://prezi.com/72rlha79knaz/the-geometry-of-ballet/ but with different explanations. This prezi explains how geometry helps dancers as well as how rotation, translation, and reflection are all involved in ballet. This prezi also explains the meaning of the term transformation in geometry.

Although this prezi had a few more grammatical errors than the other one, it still had useful information. It had good explanations, and a lot of pictures to demonstrate what was being explained.

# Module One Post Twelve (The Geometry of Ballet)

Although this is a Prezi it was still quite useful and had food information. This Prezi explains basic geometry, reflections, translations, rotation, and symmetry in ballet. When doing a pirouette a dancer is using rotation. The center of rotation is placed either on the ball of the foot or on the toes, depending on whether or not the dancer is wearing pointe shoes.  If a dancer is slouching or sitting on one hip then it won’t be a proper reflection and they won’t be symmetrical.

This was useful because it had a lot of pictures and videos to go along with the information. It also had good examples and everything was explained very clearly. I didn’t have any other resource that talked about rotations and translations, so this slideshow was very useful.

I found another prezi on geometry in ballet. This prezi has more typos then the other one but it does have useful information. This prezi explained that geometry has helped ballet dancers and it gave new information on how ballet uses rotation, translation, and reflection.

This was useful because it gave new examples of how ballet uses geometry. The explanations were very good. And it Incorporated pictures so it helped me understand how ballet had that specific type of math involved in  it.
