How I can add points to curve that has been plotted as parametric plot?

I am working on the brachistochrone example and I want to plot part of the cycloid, direct line and some combinations of them into same image.

How I can do this?

    $\begingroup$ Have you seen the options Epilog and Prolog? You can also use Show[] to combine your plot with other Graphics[]. $\endgroup$ – Michael E2 Aug 21 '16 at 19:40
