Multiple Kosnita Menggunakan Incenter Dan Centroid Melalui Excenter
Kosnita’s theorem is usually constructed using circumcenter-circumcenter.
In this thesis, Kosnita’s theorem is developed by using incenter-circumcenter,
incenter-incenter, incenter-centroid and centroid-centroid through excenter
triangle. The proof of this theorem uses the simple geometry concept such
as bisector, centroid, orthocenter and congruency. In this thesis it can be
proved that the concurrency point is the extension line from the excenter to the
Kosnita’s point.
Keywords: Kosnita’s theorem, excenter, incenter, centroid
