Question

Which graph shows a method for finding the image of point D if the parallelogram is reflected across the dashed line?

Answer 1

The third option with the right angle

Explanation:

By creating a perpendicular line through the line of reflection (the orange dotted line) and the point "D" we can measure the distance of D from the line of reflection. Then draw "D'" using the distance of the "D" from the line of reflection.
