[newbie] Geometry proof, step-by-step

Hi. I'm new to Geogebra and am already very impressed! I'd like to use it to illustrate some stages of a geometry proof and would welcome some pointers for how to do that the "right" way.

Background: The question I have in mind starts with a triangle and some carefully-constructed points (let's call this the "skeleton"). The proof amounts to spotting four cyclic quadrilaterals, one by one, and I would like to illustrate this with four separate diagrams, each built on top of the same skeleton. I don't need the diagrams to all be part of the same Geogebra worksheet, as I'll probably export them to a document anyway (the user does not need to interact with the diagrams).

Confused by layers: Thus far, I have been using the online version of Geogebra at https://www.geogebra.org/ca... . I have no trouble producing the skeleton (layer 0) and gradually layering the first cyclic quadrilateral on top of it (layer 1). I guess I could construct layers 2,3,4 for the other cyc quads in the same manner, but then how do I show/hide layers? (Apologies if this is obvious: remember, I'm new here!)

Confused by scripts: As I worked through the construction, I could see the GGBScript commands appearing in the left-hand panel. Great, I thought, I can export those commands and somehow edit them to produce each figure in turn. But I can't see how to do that, and anyway the script by itself wouldn't capture the global settings (like font size) that I've selected. I can download as *.ggb, but that does not appear to be directly editable.

Hopefully that gives you a flavour of what I'm trying to do. So what's the right way of doing this sort of thing? Maybe I shouldn't be using the online version of Geogebra at all?

Many thanks.
