There are four points with coordinates: 2,3;4,9;1,6;3,10. How to use Python to draw one perpendicular bisector between (2,3) and (4,9); the other perpendicular bisector between (1,6)ºÍ(3,10); then, makes the output like: l1 a b c l2 a b c (Note: l indicates the perpendicular bisector with equation ax + by = c.) Plus the intersection coordinates of the two perpendicular bisectors: x,y
