    Is there a document that anyone could share that shows all of the button labels in GeoGebra? Using the App on the IPad can be difficult because the directions/labels for each button are not shown on the IPad but are shown on the laptop version.

    How do you find the perimeter of a polygon using Geogebra? Thanks for your help.

      If you create an actual polygon (using the tool) you can click on it with the "distance/length" tool in the menu. The perimeter will show up. You could also use the input box to find "p = a + b + c .." etc and then display this using the text tool.

      Thanks for your help Mr. Weissburg. I was trying to measure without having drawn a polygon, which doesn't really work.

    Has anyone used the Geogebra app on ipad with classes? I'm keen to use it but am struggling to do some of the most basic things on the app version.

    Is it possible to change the scales on the axes? I can zoom in and out but it changes both axes by the same amount. Can I get an x axis from -10 to 10 and a y-axis from 0 to 200 for example?

    Also is it possilbe in the app to graph trig functions in degrees? I know how to do it on the computer but it requires the use of the "alt" key which doesn't exist on the ipad.

    Any help/advice greatly appreciated.

      Hi,

      * there is no button / gesture to change axes ratio at the moment, you can type SetAxesRatio[360,1] in input bar. We would like to improve that for next release -- https://dev.geogebra.org/trac/ticket/4166 .

      * the degree symbol is among the symbols below the input bar (on the left side of pi), so you can type sin(x°).

      Cheers,
      Zbynek

      Thanks - that's a massive help. I can't belive i didn't see the degree symbol!

      Is it possible to determine the scales on the axes? Eg set the intervals for the scale on the x axis to be 30 or 90 rather than the 50 or 100 it snaps to?

    Help!
    I am trying to create a geogebra activity for area of parallelograms. I want to start with the kids being able to drag a base along a line and see the area change. The issue I am having is that point can move vertically as well as horizontally. Can I limit it to horizontal motion? I have tried a few things, but cant seem to get this.

    Thanks!

      You can create a horizontal line and attach the point to that line. Then if you hide the line, the point will still only be able to move horizontally.

      Cool idea, Josh. Did you get it to work?
