Figure A is a heptagon in the shape of an arrow. A transformation has been applied to produce image A'. What type of transformation has been applied to heptagon A?
This transformation is not a translation since the direction of heptagon A' is different from the original heptagon, A. Heptagon A' is the mirror image of heptagon A. This transformation is a reflection in the x-axis since both shapes are the same size and the image is reflected (upside down). The tip of heptagon A and the tip of heptagon A' are both 2 units from the x-axis.
