8M: Geo QC (Reflections) learn vocabulary
 1. A reflection is a transformation that does not change the shape or size of a figure. Therefore, wesay the pre-image and image are ....congruent 2. A commonly used word to describe reflections is: flip  3. Tell whether the transformation appears to bea reflection.  No, not a reflection 4. Tell whether the transformation appears to bea reflection.  Yes, reflection  5. Tell whether the transformation appears to bea reflection.  No, not a reflection 6. When a reflection is created, there are twoimages.  The image that is there to start is calledthe where as the figure that is drawn after thereflection is called the To make sure the second firgure is properlylabeled, tick marks are put after the points, like A'.  This is pronounced A Term NOT used:pre-imagereflection line?imageprime 7. Reflecting a coordinate across the x axis results in:(x,y) → _________(x, -y)? 8. Reflecting a coordinate across the y axis results in:(x,y) → _________(-x, y)? 9. If the point (9, -2) is reflected across the     y-axis, the image point will be ...(-9, -2) 2-24-46-62-24-46-68-810-1010.
