    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.

    In our school we need to create extensive library - on line resources to be of high quality.
    Can some help me in getting General sites such as Questia, Brittanica, maybe there are others specific to subjects but I would prefer general sites.
    Thank you.

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

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

    At our school we keep entrance test on Science , English and Maths for the new admission students to check their entry level irrespective of curriculum. Presently we give them hard copies of the questions papers and make them write on the sheet and we give it to the respective teachers for correction and get it back and do the marks entries and conclude the admission.
    I found it really difficult.
    I am thinking to keep the entire assessment process on line so that the tool does the self grading and brings our easy.
    i myself found some websites like https://testmoz.com/ , http://www.thatquiz.org/ , http://www.aplusclick.com/
    But i find mostly all the above websites for maths.
    Any ideas about tools or websites to keep online entrance assessment (for science and English)
    I would like to know what ideas you follow for the above issue.

    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.

    • GeoGebra - 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

    • Mr. Tilston - 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?
