We discuss themes on Triangle Geometry
(Triangle Points / Lines / Circles etc)

CONJECTURE (was: Re: More Reflections in bisectors) Here is an analogous conjecture to that one in messages #17925-6 (Neuberg cubic) Let ABC be a triangle, A'B'C' its medial triangle and P a point on the Posted - Sat Jul 4, 2009 12:38 pm	xpolakis Offline Send Email
GUINNES RECORDS !! (was : Re: PARALLELOGIC CENTERS) [APH] ... Francisco verified that it is true for P = O,H,G,N. (is it true for all points on the Euler line ?) He has also computed the coordinates of the Posted - Sat Jul 4, 2009 11:45 am	xpolakis Offline Send Email
Re: PARALLELOGIC CENTERS [APH] ... Francisco told me it is not true in general. However, it seems it is true for P = O For P = H, it seems that La,Lb,Lc are concurrent. Antreas Posted - Fri Jul 3, 2009 8:29 pm	xpolakis Offline Send Email
Re: More Reflections in bisectors For P = I the concurrence point is the same point L that in Hyacinthos message #17947 Posted - Thu Jul 2, 2009 8:13 pm	garciacapitan Offline Send Email
Re: More Reflections in bisectors Let ABC be a triangle and P = (x:y:z) a point. Denote: A* :=(Perpendicular from B to CP) /\ (Perpendicular from C in BP) B* :=(Perpendicular from C to AP) /\ Posted - Thu Jul 2, 2009 3:13 pm	xpolakis Offline Send Email
