In geometry, Euler's rotation theorem states that, in three-dimensional space,
any displacement of a rigid body such that a point on the rigid body remains fixed,
is equivalent to a single rotation about some axis that runs through the fixed point.
It also means that the composition of two rotations is also a rotation.
Therefore the set of rotations has a group structure, known as a rotation group.
