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.

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.
Two
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.
