Thanks



[vincenthich]

this helped me a lot. Thanks!

When you go to put in the points which cross at each axes use the "Intersect Two Objects" tool and click on the axis and then the line which is perpendicular to it. This seems to solve the problem of these points also moving and giving you different polygons.

Actually, I can move B and D along with C, even though they are under "Dependent Objects"

I'm following your steps exactly but when I drag point C it is not staying in the shape of a rectangle. A, B, and D will not move nicely to make another smaller or bigger rectangle and I end up with weird shapes. A won't move at all, it is staying at the origin. Any suggestions?

Very interesting for begginers with Geogebra. Notice that you can also use the internal perimeter[...] and area[...] functions.
