Answer the following questions dealing with point reflections.

 1. The image of the point (4,-3) under a point reflection in the origin is (-4,3). True False Explanation Remember (x,y) becomes (-x,-y).

 2. Under a point reflection in the origin, the image will look like the original figure turned up-side-down. True False Explanation This property of point reflections (symmetries) can help you determine if your answer is correct.

 3. When dealing with a point reflection in the origin, the origin is the midpoint of the line segments connecting each point to its image. True False

 4. This graph illustrates a point reflection in the origin. True False Explanation Check the coordinates of any point and its image.  They are not the same distance from the origin.

 5. This graph illustrates a point reflection in the origin. True False Explanation All of the coordinates follow the rule: (x,y) becomes (-x,-y).
