Answer :
It is primarily rotation that does not preserver orientation, since a rotating object's perspective on its surroundings changes with each step of the rotation slightly.
Answer;
Line reflection
Line reflection is the rigid motion that does not preserve orientation.
Explanation;
-Line Reflection does not preserve orientation., it preserves the distance, and is an example of opposite isometry.
-Dilation (scaling), rotation and translation (shift) preserves the orientation.
-Orientation or attitude of an object is part of the description of how it is placed in the space it occupies (the order of points around a shape in a specific direction)..
-Rigid Motion is a transformation that preserves distance and angle measure.
