Students often construct a polygon into a wrong part of the plane. Pre-showing the outcome will be helpful.
How can ggb pre-show the outcome of something that hasn't been built yet?
🤔 Anyway, every polygon can be dragged after selecting the Move tool.
First you enter the number of vertices n, then you put the first vertex, then GGB pre-shows you the regular n-gon depending on the second vertex. When you put the second vertex the polygon is ready. It's just like the tool 'Perpendicular line' – if you choose the line first, then GGB pre-shows the perpendicular line depending on the point.
I see a preview of polygon when I am building it in desktop
do you talk about some app?
excuse, sorry, no, I do not think in "regular"
