Problem 4.6A
After creating the two reflections and messing around with comparing distances between certain points I found that the distance of BB'' and HI are related in the sense that BB'' is always double HI. This is true no matter how you drag the figure. You could do this transformation by just measuring the distance of the original figure to the first parallel line (BH) and using that to place the figure this distance from the second parallel line. (BH=IB")
