parabola
Any point on a parabola is the same distance from the directrix as it is from the focus (F). AC equals CF and BD equals DF.

pa·rab·o·la

 (pə-răb′ə-lə)
n.
A plane curve formed by the intersection of a right circular cone and a plane parallel to an element of the cone or by the locus of points equidistant from a fixed line and a fixed point not on the line.

[New Latin, from Greek parabolē, comparison, application, parabola (from the relationship between the line joining the vertices of a conic and the line through its focus and parallel to its directrix), from paraballein, to compare; see parable.]

(Mathematics) a conic section formed by the intersection of a cone by a plane parallel to its side. Standard equation: y2 = 4ax, where 2a is the distance between focus and directrix
[C16: via New Latin from Greek parabolē a setting alongside; see parable]
