Hi from India. I accidentally came to this software and your tutorials and its a gem. I wish we had these tools during my school days. Its fabulous and your teaching style is very good. You have kept video sizes to optimum so that we do not loose concentration and focus and also it is nicely planned from basics to advanced tools. Great job.
Here's how to hide the labels on the vertices. Before you build anything, go to the menu you that show at 6:19. Just below "Rounding" is a setting for "Labeling". Change it from "Automatic" to "No New Objects" and you won't see the labels on the vertices. It may also work if the setting is changed after you've made the polygon, but I'm not sure. I always start my models with it set to "No New Objects", then enable just the labels I want showing. Note too that the minimum value for the n slider can be as low as 1 if you think of n as the number of equal divisions of the circle you're making rather than the number of sides on a polygon. When n = 1, you have a single division resulting in B = B' which looks like one point. When n = 2, you have a digon which looks like a line segment through the center, and for higher values of n, you have the famillar n-gons staring with a triangle as you have in your example. When n = 0 then your central angle (ca) is undefined because you're dividing by 0 (Geogebra shows it as infinity). The dependent objects B' and poly1 are therefore also undefined. You can also set the minimum value of n to a negative number, if you change the definition of poly1 to use abs(n) instead of just n. Then the polygon will be constructed outside of the circle because B' rotates around the circle in the opposite direction. This may not be what you want for your application, but it's an interesting exercise. Thanks for posting this series.
Hi David. Thank you very much for your generous comments and explanations and some of them are really interesting (like the negative value of n making the polygon appear in the opposite direction). I know that if the order of click is reversed, the polygon will be constructed in the opposite direction but I have not connected it to the negative value. I am familiar with the "No New Object" option but it appears that it doesn't work in that particular example. Hopefully this series (despite my horrible English speaking skill) will help GeoGebra newbies. Keep safe.
@@geogebraist8512 I assume you're using GeoGebra 6. I can confirm that the "No New Objects" setting does work as desired with GeoGebra 5 classic, which is what I use, but as I said, you have to enable the setting before you make the polygon for the first time. I think that's because once the vertices have been created one time, they are no longer "new objects". Again, I'm not sure if version 6 works the same way or not. If not, then it might be a good question for their forums. Thanks again. I look forward to learning some more specialized tricks and techniques after you get more of the fundamental aspects covered in your upcoming videos. Keep up the good work.

I would like to thank you for making this series....Extremely helpful

Thank you. Yes, I tried the setting to "No New Objects" before creating the polygon and it worked.
Hi, thank u so much, u saved my life and help to earn good mark, and also explain me how to use animations in Geogebra.
Sir, could you please tell me how to draw circumscribed polygon using geogebra with the help of a slider
I hope my video may help you to draw circumscribed polygon using slider. th-cam.com/video/7hM43_wTuJk/w-d-xo.html
Hi! Now how do I circumscribe a polygon around a circle?
Here how to find perimeter instead of area
