how to draw incircle of a triangle fast?

I want a quick way to draw the in-circle of many triangles.

If drawing a circle, has an option to use three tangents, that would help a lot.

Other ways could be to write a macro inside GeoGebra to draw the angle bisector for each apex and find the cross point. (I am not sure if it is possible in GeoGebra to write macro)


Any help in drawing the in-circle of a triangle is highly welcomed.


I am using GG 5.0.148.0-3D

Dear Mathmagic


Tool1 draws the triangle with incircle in the same time.

I already have the triangle and only want to draw the incircle.It is possible to use this tool. I can draw the triangle again, haveing three apexes.


Tool2

Could you please elaborate this tool?
