WebIn 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 … WebRotating shapes about the origin by multiples of 90° ...
