Any
of
a
family
of
curves
defined
as
the
locus
of
points
p,
such
that
each
p
is
on
a
line
that
passes
through
a
given
fixed
point
P
and
intersects
a
given
curve,
C,
and
the
distance
from
p
to
the
point
of
intersection
with
C
is
a
specified
constant
(note
that
for
nontrivial
cases
two
such
points
p
satisfy
the
criteria,
and
the
resultant
curve
has
two
parts).
