You've got tools and commands, so can you explain your problem? You only have to look which version (not) tu use: look at https://www.geogebra.org/m/shfwqcpr

The situation is as follows. When, for example, I draw the median of a triangle, only the point is indicated, but it is not indicated that these segments are equal. It is the same with the bisector, the geogebra does not denote the equality of angles with arcs.Still have a problem, how to automatically specify the point of contact of two or more circles?

How do I get the touch points of circles automatically?Or is it impossible?

I think: what you are looking for, GGB does this not do automatically.

(but is a nice idea)

And how to do it not automatically?

Indeed it's nice when focussing on the properties of these lines. But would I want them to appear in any case when drawing them as auxilliary objects in whatever construction? Maybe not.

Anyway you can create custom tools whit those extra's you want to appear for specific lines.

Tell me, please, what kind of tools?

See the tutorial: https://www.geogebra.org/m/...

You can select the starting objects and the end objects so to show all what you need if the existing tools don't exactly bring you what you want and make a new tool for it.

For example, I want to put serifs on the segments that are divided by the median. It turns out that I need:

1) Put the intersection point of the median and the side

2) From this point, draw segments with the ends of the original segment

3) Go to the style and put serifs.

Couldn't it be easier?

1) use the Angle tool

2) change the Decoration of the angles

I tried it, but it didn't work

Please post your .ggb file and explain which bit didn't work

Here is an example. In order to indicate equal angles in the figure when bisecting, I need to: 1) Mark the bisector, 2) Mark each of the half corners; 3) So that the corners do not merge, you need to go to "Styles" and increase the size. Couldn't it be easier?
