Two circles meet at points A and B. A line through B intersects the first circle again at K and the second circle at M. A line parallel to AM is tangent to the first circle at Q. The line AQ intersects the second circle again at R.(a) Prove that the tangent to the second circle at R is parallel to AK.
(b) Prove that these two tangents meet on KM. trigonometrygeometry proposedgeometry
