focus
There are two points: the foci.
focus
No there can never be a single point. But yes there are two such points called foci( each called focus) that helps to define an ellipse. An ellipse can then be defined as a curve which is actually the locus of all points in a plane,the sum of whose distances from two fixed points (the foci) is a given(positive)constant . This is further expressed mathematically to obtain the equation of an ellipse.
An ellipse is a shape on which the sum of the distances from every point to two points inside called the foci (focuses) is always the same number. A circle is an ellipse with both foci (focuses) at the same point.

Ellipse is a term for an oval. Specifically it is a shape where the sum of the distance of every point on the ellipse to two points, called the foci, is equal.
An ellipse is a shape on which the sum of the distances from every point to two points inside called the foci (focuses) is always the same number. A circle is an ellipse with both foci (focuses) at the same point.
A circle is an ellipse with an eccentricity of zero. Both foci of that ellipse are at the same point. In the special case of the circle, that point is called the "center".
Someone wanting to find information about the Ellipse products can find it online. Someone can look at the adobe site, as well as the Ellipse site itself to find all the information needed.
Ben drew an ellipse as a plane curve with edges not parallel to its axis.
Both foci of any ellipse are always in the same plane.If they're both at the same point, then the ellipse is a circle.
An ellipse is very eccentric when its foci are far apart.The closer one focus is to the other, the less eccentric the ellipse is.When when both foci are the same point, the eccentricity is zero, and the ellipse is a circle.
Essentially an ellipse is a circle rotated about an axis without changing the point of view.
