The two foci are necessary to define the location of an ellipse, but the shape depends on the eccentricity, which is related to the lengths of the two axes.
The width reduces as the length increases. The changes shape of the curve is a part of a [rectangular] hyperbola.
guadrilateral
change of position, shape, or size of figure
if you multiply all the points by one you get the same points so the shape stays the same.
The two fixed points are the foci but these do not define the shape of the ellipse. You also need to know the eccentricity.

A liquid is a state of matter that has a defined volume but no defined shape. In a liquid, particles are close enough to have a fixed volume, but not in a fixed position, allowing the substance to take the shape of its container.
An ellipse, a hyperbola.
The shape that defines the orbit of planets around the sun is an ellipse. An ellipse is a closed curve in which the sum of the distances from any point on the curve to two fixed points (foci) is constant.
a sphere
Sphere, Hyperbola and Flat.
Coplanar means "on the same plane". A plane can be a figure or shape like a rectangle. Coplanar points means points that belong on the same plane.
One key difference between liquids and gases is their ability to maintain a fixed volume. Liquids have a definite volume, whereas gases do not have a fixed volume and will expand to fill the container they are in.
A circle is a closed curve where all points are equidistant from a fixed point called the center. It is a two-dimensional shape with no corners or edges.
A right hyperbola shape.
It is the set of points, in 3-dimensional space, defined by the intersection of two planes which define faces of the shape.
