9. A circle C has equation(x-k)^2+(y-2k)^2=k+7 where k is a positive constant.(a)Write down, in terms of k,(i) the coordinates of the centre of C,(ii) the radius of C.Given that the point P(2 3) lies on C(b) (i) show that 5k-17k+6=0(ii) hence find...
there angle bisectors meet(the incenter).Construct the angle bisectors of A and B .They intersect at the incenter(I).The incircle is also tangent to all sides of triangle so construct the perpendicular from the incenter to AB.Using IZ as the radius,the incircle can be constructed.....
