Rotation: Any 2D rotation transformation is uniquely defined by specifying a centre of rotation and amount of angular rotation, but these two parameters don't uniquely define a rotation in 3D space because an object can rotate along different circular paths centring a given rotation centre and thus forming different planes of rotation. Created with Raphal. 5. A preimage or inverse image is the two-dimensional shape before any transformation. can any rotation be replaced by a reflection A reflection leaves only the axis of rotation fixed, while a reflection followed by a different reflection leaves only one point fixed-the intersection of the two axes of reflection , so it must be a rotation since only a rotation leaves a point fixed.
