Step by step description: 1.Start with a circle and a point F1 inside the circle. 2.Draw a line L from a point P on the circle to F1. 3.Draw a line M perpendicular to L and passing P. 4.Repeat step 2 and 3 for other points P on the cricle. 5.The envelope of lines M is an ellipse with a focus F1. If the point F1 is outside the circle, a hyperbola is generated.t7Q@1 ~~ K~,`K~ ,`K K~ $Conics by Negative pedal of a Circlet ȱA@)@mձ@CQC tZ_BH@G@@F@J@%KCC t"'0F(1)0(945PF{l:1}76476946T,.,,46@ # DSC tF@?c3 qea q` rc s!g swh tCQCHCF%5?F%5?t\aPFocus_P/_ ""__T_|@-DC  t 'r K ) +c +CQC DSC?te P (Drag Me)945P476476946T,.,,46@ #8c t$n!
