Part II options should you the distance of the pre-image points to the line of reflection(Mirror) and the image points to the line of reflection(Mirror). Check the boxes to show the distances. 4. Part III shows the coordinates of the pre-image and the image. Check the boxes to show the coordinates. 5. Continue to move the points around to find patterns in the distances and coordinates from Part II and Part III. 6. Answer the questions below.
