For a triangle and three points
,
, and
, one on each of its sides, the three Miquel circles are
the circles passing through each polygon vertex
and its neighboring side points (i.e.,
,
, and
). According to Miquel's
theorem, the Miquel circles are concurrent in
a point
known as the Miquel point. Similarly, there are
Miquel circles for
lines taken
at a time.
