Abstract "Middle school mathematics study" in 2016 fifth the "Conic "midpoint chord" of a theorem and its application" in the scope of application of theorem is confined to elliptic and hyperbolic field, this paper further expands the theorem of conic curve "midpoint chord" to the field of parabola.
Keywords conic curve "midpoint string"; judgment theorem; expansion; parabola
