Yes, they do.
When ballet dancers do the splits in the air it is usually called a spilt leap or a center leap.

open your legs wide open
In ballet, you do not necessarily have to be able to do the splits. Now, you will most likely be required to do them if you are in a professional company or professional show.
It's not something that you HAVE to be able to do. But it definitely helps to be more flexible.
Ballet hand down. In cheerleading, splits are pretty much the only thing needed for toe touches and maybe some tumbling. In ballet, however, we need splits, straddles, oversplits, and so much more. We are always using our flexibility is jumps, turns, partnering, balances, etc etc. I only know one cheerleader who can do a split and it isn't even a good split. Ballerinas sleep in splits.
Splits, leaps, double/triple pirouettes, fouettes and point.
if you mean what is a turn in ballet called? it is a pirouette.
Ballet in Spanish is actually the same "Ballet"
Either the ballet celebration or the ballet festival
You are Flexible.
