1. Play with the diagram.
2. When you focused on reflecting each point across the line, what was the one guiding idea that was in your mind as you were making your decision? Were you right?
3. Move the original segment (on top) further away and closer to the line of reflection. Then reflect the points again. Is there an occasion where estimating the reflected points is easier or harder? If so, why or why not?
