You can GeoGebra very nemt measure omkredsen af ​​polygon.

1. You will first have constructed your polygon using fx. -button or via input field.
2. I input-feltet (you turn the input field to the submenu show) write then

   circumference[polygon1]

   (Polygon1 you can switch out the names of the polygon, as you will find circumference of)

3. In algebra, you can now see the circumference of your polygon. (See numerically)
4. You can rename the radius of name (used as a starting point only ever a letter) ved at højreklikke på bogstavet/navnet i algebravinduet og derefter vælge “omdøb”.

TIP! Try to draw the polygon and see, what happens to the perimeter.
