The linked diagram shows an alternate route to finding the symmedian point by using two sides with corresponding vertex. A short spread on a divider compass expedites bisecting of angles without the aid of a protractor. Dividing a side in half is done by a few trials of the divider. Transposing the bisected vertex and bisected side is facilitated with a circle.
It is not practical to be using a symmedian point when laying down a round of stars but I do see a place for it where a round of GPS satellites are automatically analyzed for ultra precise positioning.
