Text typed:

In two dimensions we say that a rigid body has only one rotational degree of freedom, whereas in three dimensions we say that a rigid body has three rotational degrees of freedom. This might lead you to infer that in three dimensions you need to have three scalar quantities to represent a body's rotation. Indeed, this is the minimum requirement.
