Be careful when using the EntityPitch command. It will return duplicate values at different points of rotation. It's better to use a variable to store the pitch value.
EntityYaw and EntityRoll return useful values, but they may not be the values you expect. I'd recommend experimentation.
EntityPitch, EntityYaw, and EntityRoll can be used as a set to take a snapshot of the total rotational state of an entity, however.
Here's some code that can be used to view the rotational values returned by these commands:-
