Get all points in the plane
Bolzano shared this question 2 years ago
Hello, I am very new to Geogebra and am trying to make a very simple demo for a presentation. I want to be able to make a polygon dynamically, meaning I don't have to first place the points and only then create the polygon, rather be able to add a point which automatically joins the list.
Is there a simple way to achieve this? for instance by some command which returns a list of all points? I didn't find one in the manual.

You don't have to create points first to create polygons after that. Clicking in the graphic and closing by clicking on the first point creates a polygon. But what you mean by "add a point which automatically joins the list" is rather cryptic" as is "a list of all points" since the number of all points is infinite.
If you mean if you just can type coordinates of not yet existing points, indeed, just try and see.
You can define e.g. Polygon((1,2), (4,3), (2,4))
