That's the definition of an ellipse.
An ellipse does not have any parallel lines in the traditional sense, as it is a continuous curved shape. However, if you consider the tangent lines to an ellipse at different points, there can be pairs of tangent lines that are parallel to each other. In general, the concept of parallel lines is not applicable to the entire structure of an ellipse.
An ellipse does not have parallel lines in the traditional sense, as it is a smooth, closed curve defined by its geometric properties. However, one can draw tangents to the ellipse at various points, and some of these tangents can be parallel to each other. In a broader mathematical context, while the ellipse itself does not possess parallel lines, the concept of parallelism can apply to lines related to the ellipse, such as its axes or tangents.
In the context of an ellipse, each point marked with a dot is called a "focus" or "foci" (plural). The ellipse has two foci, which are positioned symmetrically along the major axis. These points are crucial in defining the shape and properties of the ellipse, as they relate to the distances from any point on the ellipse to the foci.
Yes the ratios are sometimes equal to each other.
The two points that define the shape of an ellipse are called the foci. An ellipse is the set of all points where the sum of the distances from each point on the ellipse to the two foci is constant. The distance between the foci and the center of the ellipse determines its eccentricity, influencing how "stretched" or "circular" the ellipse appears.
An oval is an ellipse
The shape of the orbit of each planet is an ellipse. An ellipse is a geometric shape that is like a flattened circle. The Sun is located at one of the foci of the ellipse, not at the center.

Johannes Kepler discovered that the Earth revolves/orbits the Sun in an ELLIPSE. He also discovered that the Sun is NOT at the centre of the ellipse, but at one of the foci ; (plural of focus). The other focal point being 'blind'. From this we have the definition, that as the Earth orbits the Sun , 'It sweeps equal arcs in equal times'. As the Earth orbits, it speeds up and slows down. It is moving at its fastest when passing the Sun at it nearest point ( perigee) and slowest when at its furthest point ( apogee). Have a look in Wikipedia under' Johannes Kepler.

It is an ELLIPSE. The Sun is NOT at the centre of the ellipse, but at one on the foci. Not only is the orbit elliptical , but this ellipse over time fattens ( becomes nearly circular) , or becomes a very narrow ellipse. The foci ( plural of the noun 'focus'), are two points inside the ellipse, on the major axis, where is you draw an ellipse with pins paper and string, are the two points were the pins are inserted. This ellipse does not quite close up. Each year there is a slight overlap in the orbited track . This has been observed with Mercury's orbit. Because the Sun is at one of the foci , the Earth's orbital track , speeds up near the Sun and slows down furthest away from the Sun. Also Equal Arcs of this orbit are swept in equal times.

Elliptical
The two points that define the shape of an ellipse are called the foci. An ellipse is the set of all points where the sum of the distances from each point on the ellipse to the two foci is constant. The distance between the foci and the center of the ellipse determines its eccentricity, influencing how "stretched" or "circular" the ellipse appears.
