hey i have tried to do this and it works up until 1:30 but then if i click or do anything, the circles vanish. What do i do? (it is for school)

@manchesterunited1232 Is that problem with the online Geogebra program? I suggest you to download my file (or open your file) with the offline installed version of Geogebra (which can also be downloaded from the Geogebra website).

@jocaojocao1

It should continue to work in version 4. Maybe you check whether the objects A1, r, t, P are all created and named in other ways.
