How to Create a CUSTOM TOOL in GeoGebra

Creating a CUSTOM TOOL provides an added convenience for students and teachers who use GeoGebra to explore and discover math concepts. Having a quick tool like this can be a huge time-saver for students. For example, in a unit where students are studying about right triangles, it is would be convenient to simply have a RIGHT TRIANGLE TOOL (like this) to quickly plot a right triangle. As a result, students can have more time to proceed with an investigation relating to right triangles. Here, we will learn how to create a custom tool that immediately creates a right triangle after the user simply plots 2 points.

Is it possible to create a tool that given a line s and a value k, it draws a line parallel to s and distancing k from it?

[@TimBrzezinski]

Yes

How can people find out how the custom tool was defined? For the standard tools you can look it up online in the geogebra help pages, but for custom tools it seems there is no convenient way to inspect how the tool was defined.

How to make tool with Fix size?

[@andreassteiner3134]

I think it might work by using circles with fixed radius as underlying elements of your tool for example (but I didn‘t check on that)

With over 40 years of computing experience and more than one degree in mathematics I've spent the entire afternoon trying to create a custom tool in GeoGebra desktop and to get it to stick on the toolbar: I've given up! Apparently I have been allowed to "save" a file containing a representation of demo tool ... but there is absolutely no way I can find to get it back into the application. I'm afraid I'm obliged to conclude that the functionality is either broken, or else it is too obscure for even advanced users .... (the reason I'm doing this is because a teacher who uses GeoGebra every day has asked me for help!)
