Kieroid
Let the center 
of a Circle of Radius 
move along a line 
. Let 
be a fixed point located adistance 
away from 
. Draw a Secant Line through and 
, the Midpoint of the chord cutfrom the line 
(which is parallel to ) and a distance 
away. Then the Locus of the points ofintersection of 
and the Circle 
and 
is called a kieroid.
