Let
A & B be two fixed points on a fixed straight line.
Two circles touch this
line at A & B respectively and tangent to each other at M.
When the circles
vary, the locus of M forms
(A) A
circle with diameter AB minus points A & B.
(B) An
ellipse with major axis AB minus points A & B.
(C) An
ellipse with minor axis AB minus points A & B.
(D) A
square with diagonal AB minus points A & B
