An ellipse is a planular conic and is two-dimensional, meaning it de facto only has one face.
In this context, an ellipse is equivalent to a circle: it has one edge and one face and no vertices.
Ellipse has no sides and

No. Both foci are always inside the ellipse, otherwise you don't have an ellipse.

There are any number of shapes without flat faces including: > circle > ellipse > blob
An oval shape, often referred to as an ellipse, is a two-dimensional figure and does not have faces in the same sense that three-dimensional objects do. It has a smooth, continuous curve with no edges or vertices. Therefore, it can be said that an oval has zero faces.
Ellipse has no sides and
An ellipse has 2 foci. They are inside the ellipse, but they can't be said to be at the centre, as an ellipse doesn't have one.
None; an ellipse is a smooth curve, not a line.
An ellipse has rotational symmetry of order 2.
An ellipse has two focal points. These points are located along the major axis, equidistant from the center of the ellipse. The sum of the distances from any point on the ellipse to these two foci is constant, which is a defining property of an ellipse.

None.
An ellipse has two lines of mirror symmetry: the line that includes the two foci of the ellipse and the perpendicular bisector of the segment of that line between the two foci.
