Coordinate system

Good evening,


Is it possible to enter a coordinate system in GeoGebra after the construction? For example, I built a triangle I made some cevian in it – and I want now that the length of this cevian in the chosen coordinate system is equal to one (ideally, to any number a≠0).

I think better to change the cevian and others objects doing an homotecy than to change the system of coordinates. so the length of cevian is 1 (or a) really

then you can do zoom using zoomin() or zoomout() and the information of corners
