The Siebeck-Marden theorem
Notes
You can drag the triangle vertices A, B, C and/or change the parameters.
If you set the inellipse will touch the three triangle sides in their midpoints (and is called Steiner inellipse).
The complex polynomial equation and solutions are in the CAS view (not shown online)
