A CHARACTERIZATION OF CONIC SECTIONS
Kim, Dong-Soo,Kang, Seung-Hee The Honam Mathematical Society 2011 호남수학학술지 Vol.33 No.3
We study some properties of tangent lines of conic sections. As a result, we establish a characterization of conic sections.

SOME EQUIVALENT CONDITIONS FOR CONIC SECTIONS
김동수,서수정,범우인,양덕주,강주연,정지은,송부선 한국수학교육학회 2012 純粹 및 應用數學 Vol.19 No.4
Let A and B denote a point, a line or a circle, respectively. For a positive constant a, we examine the locus CAB(a) of points P whose distances from A and B are, respectively, in a constant ratio a. As a result, we establish some equivalent conditions for conic sections. As a byproduct, we give an easy way to plot points of conic sections exactly by a compass and a straightedge.
