Assertion: parabola's focus | /r/HasAspect | finite coordinates
Facets:
value: for the ellipse
type: TRANSITIVE-OBJECT
Source sentences:
text: For the ellipse, both the focus and the center of the directrix circle have finite coordinates and the radius of the directrix circle is greater than the distance between the center of this circle and the focus; thus, the focus is inside the directrix circle.
