Help with Hanger Diagrams

I got this idea from Nathan Craft and his 1 step hanger activity. My problem is with slide 6. The shapes don’t move as one when you enter in a value bigger than the correct answer. Then if you enter the correct answer it does the same thing.
Slide 6

In the graph, the y coordinates for polygon(x_4, y_4) all need to have “-w” instead of “+w”. (I also had to shift the coordinates a bit to make the box line up correctly.)

Thank you so much. It worked
