What would be the answer if ΔABC is equilateral and "ΔABC's anticomplementary triangle" is replaced with "ΔABC's circumcircle"?

*
NOTE: The anticomplementary triangle of a given triangle
is formed by three lines. Each line passes through
a vertex of the given triangle and is parallel to
the opposite side.
*

*
NOTE: The circumcircle of a given triangle is the unique
circle which passes through each of its vertices.
