Nine points circle
(Geom.), a circle so related to any
given triangle as to pass through the three points in
which the perpendiculars from the angles of the triangle
upon the opposite sides (or the sides produced) meet the
sides. It also passes through the three middle points of
the sides of the triangle and through the three middle
points of those parts of the perpendiculars that are
between their common point of meeting and the angles of
the triangle. The circle is hence called the nine points circle
or six points circle
