·It will be larger than Triangle ABC because rotations and reflections change the shape or size.
·It will be smaller than Triangle ABC because rotations and reflections change the shape or size
·It will be congruent to Triangle ABC because rotations and reflections do not change the shape or size.
·It will be similar because rotations and reflections change the size.
