Messing With Lisa: Reflect

Note: LARGE POINTS are MOVEABLE.

Mess around with a reflected Lisa. Put the yellow line on the x-axis. Find the distance from one point on the preimage of Lisa to the same point on the reflected image of Lisa.

What is the distance of these points from the yellow line?

Keep the yellow line on the x-axis. List the coordinates of one point on the preimage of Lisa and the same (correlating) point on the reflected image of Lisa. What do you notice?

Mess around with a reflected Lisa. Put the yellow line on the y-axis. Find the distance from one point on the preimage of Lisa to the same point on the reflected image of Lisa.

Mess around with a reflected Lisa. Put the yellow line so that it goes through the origin (the middle) of the graph. Try to describe the distance between one point on the preimage of Lisa to the same point on the reflected image of Lisa.
