This is the half-turn image of the reference triangle about the Spieker center, so it is
congruent to (García 2014, Dalcín and Kiss 2021).
Reflecting its vertices across the corresponding sidelines of gives the inner García
triangle (García 2014).
Its vertex is the orthocenter of
, where
is the excenter opposite
, and the other two vertices
are obtained cyclically (Dalcín and Kiss 2021). Its orthocenter
is the Bevan point
, where
is the circumcenter of
(Dalcín and Kiss 2021).
The outer García triangle is perspective to the García reflection triangle at the Nagel point (Dalcín and Kiss 2021).
