# Embedding a protractor and ruler in one resource

Jessica Barr shared this question 1 month ago

I'm wanting to help my geometry team adapt a lesson related to triangle congruence for distance learning (see attached). I found one of your webinars online thought I might reach out to see if you could offer guidance or point me in the right direction. I'm very new to GeoGebra but excited to learn!

For the lesson, students will need a protractor and ruler. I found both of these resources on the Remote Learning Templates for GeoGebra Classroom but I can't seem to figure out how to get both within one activity window. If you could offer any assistance or point me in the right direction to inform my learning, I would greatly appreciate it!

There are many public activities that include a pretractor and/or ruler. In all of them a picture of the object is included and calibrated to the grid of the applet, while defining points helps you to move and use it in your construction. You can't just embed it in another file, you have to include a picture and add to it the calibrating procedure. Download a file you like, learn how the thing works, add a picture you like (you can find pictures on the internet) and apply the calibration yourself.

Or you can rebuilt your activity in a file with an existing workig protractor.

Thanks so much for your response! Do you know of a tutorial I can turn to for info about calibrating to the grid?

Maybe post the links for the two you want merged

Hi Michael,

I so appreciate everyone's time and expertise!

You'll learn everything in the algebra view of this file so you have to download the file first (use the three dot icon in the upper right corner). The in ggg you can open the algebra view. Select the points that define the center and the edge and see how they are defined. Tip if you create such a thing yourself: watch out not to use not-transparant pictures that cover other things as the grid.

Try this (GeoGebra Classic 5 has the option when opening a file to "Insert File (.ggb)")
